Flexible silicone smooths the intake tract while allowing for a range of performance intakes fitments. The ultimate in durability!

In most vehicle applications, the rubber intake elbow found in the intake system is not designed for performance or modification. They were designed to get the job done but when you add a performance filter, intake or tune, the stock elbow will start to show it weakness. The stock rubber elbows disrupt air flow as it passes over the accordion sections causing unwanted turbulence and negating the effects of intake modifications.

With high quality 4 ply construction, the Turner intake boot is strong but flexible, ensuring a secure fit on an OEM or aftermarket intake system. A smooth interior ensures unimpeded airflow, while a smooth, unassuming exterior adds to any engine bay.

Benefits:

Improved throttle response,
Increase induction sound
Increased power output - and power output, Best when paired with an ECS drop-in air filter.(ES4461001 or ES4460965)

Get the highly coveted CSL experience with your S54! Roaring induction noise, aesthetics and increased performance are just the tip of the iceberg when installing this legendary intake. Its not fair that Europe always gets the cool cars and widgets (excluding E36 LTW, thank you BMW.) The E46 CSL M3 is world renowned as one of the finest cars BMW produced. Covered with parts exclusive to the CSL model, the intake system is one of the most sought after components for non-CSL owners. The CSL intake plenum is your chance to experience the life altering CSL intake. For starters, after installation you are left with a completely transformed engine bay. You can try your very best to resist from sticking your arm in the massive inlet of the plenum but we doubt that you will be able to hold back. Turner's CSL intake plenum boasts a full carbon fiber construction with velocity stacks engineered to outflow the factory air box by over 20% and even outperforms the factory CSL air box on the flow bench because of the improved design. The CSL intake does not feature any sound dampening or silencer and allows your S54 to let out its full roar that can be heard clear through the cabin for an experience that makes you smile ear to ear. Paired with the Active Autowerke Alpha N Tune we have seen gains of up to 43 hp and 26 Ftlbs of torque in a healthy naturally aspirated S54. Performance Benefits: Airflow increased by over 20% Increased throttle response Tuning benefits far beyond the factory intake Weight reduction Roaring induction noise for both driver and spectator

When we first got our hands on a E46 M3, we were eager to release our CSL Intake. After popular demand, the experts here at Turner took it upon themselves to make a more affordable intake option. Our engineers took the original stock intake and made it better. The intake system we designed outflows the factory intake, maintains factory MAF scaling, provides increased induction noise, and looks great in the engine bay. Our intake was CAD designed inhouse to seamlessly integrate with OEM inlet ducting and stock mounting locations.
Through rigorous research, development, and testing of this intake, Turner has created their perfect version of an "Open Intake" that flows more freely than the stock intake, providing options to suit your needs for a cost-effective solution. Flow bench tested in-house at Turner, the Turner E46 M3 intake flows more air than the OEM M3 Factory intake.
Features:
Wrinkle Black Powdercoated Heat Shield Assembly with pre-installed edge trimming.
Precision fit heat shield provides fresh cool air to the intake while keeping hot engine bay air out.
Heat shield mounts in stock location with supplied hardware
Maintains OE fresh air inlet scoop.
Aluminum MAF housing maintains OEM MAF scaling.
4" conical hi-flow reusable air filter; featuring 8 ply oiled cotton gauze construction and a bell mouth inlet to maximize flow and filtration efficiency

The F-connector is located on the air intake boot and provides a connection point for the vacuum lines that run to the brake booster and fuel pressure regulator. The factory connector is made of plastic and with heat and exposure to the elements the connector becomes brittle and potentially cracks. As a result, a vacuum leak occurs which can cause poor idling issues, evap fault codes, and poor performance. 

This aluminum version from ECS Tuning is impervious to these issues, and will easy outlast the rest of your plastic and rubber vacuum system components.

E39 525i 530i

Our Performance CSL Air Filters start with a multi-layer oiled cotton construction that contains millions of smaller fibers to provide superior filtration and performance over the OEM filter. Precisely manufactured for a secure fitment to ensure all the air entering your motor is properly filtered. With the CSL E46 only being offered in Europe, the OEM air filters are produced in much lower quantities making them harder to obtain and drive up the price. Turners solution is a price effective solution that offers premium filtration with increased flow, extended service interval and lifespan.

Having a clean air filter ensures your engine is running at its best efficiency! Proper air flow will help your engine breathe, get the best fuel economy and allow full power throughout the power band. Get the most out of your CSL intake with a new Oiled High Flow Air Filter. These filters can be cleaned, oiled and reused for an extended service life.

Oiled versus Dry Filters:

Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters allow better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards.
Dry filters offer slightly lower airflow but are easier to maintain while still out performing the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.
Both dry and oiled filters flow better than stock and can be reused.
Product Features:

Direct Replacement for OEM filter
Increased air flow
Lower cost
Serviceable
Readily available
How to service an oiled air filter:

Take out your High Flow Filter
Gently tap your air filter on a smooth surface
Wash with warm soapy water a a soft bristled brush

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

BMW E46 Crankcase Pressure Regulator Valve | S54 3.2L Engine is a crucial component that ensures proper crankcase ventilation by regulating oil vapor flow into the intake manifold, preventing excessive oil consumption and buildup. Designed specifically for BMW E46 models with the S54 3.2L engine, this valve helps maintain engine efficiency and performance. BMW engines are known to experience oil separator freezing in cold weather if not fully warmed up, which can lead to howling noises and oil leaks. To ensure a thorough repair, replacing the valve cover gasket when changing the separator is highly recommended.

  • Helps maintain proper engine ventilation for peak performance
  • Reduces the risk of oil separator freezing and associated leaks
  • Direct-fit replacement for BMW E46 models with S54 3.2L engine
  • High-quality materials ensure durability and long-lasting performance
  • Recommended to replace the valve cover gasket for a complete repair

Protect your BMW's engine from excessive oil consumption and leaks by replacing a failing crankcase pressure regulator valve with this premium-quality replacement.

If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage. Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold. Includes new mounting hardware

Dinan has enigneered a new air box cover that allows  you to run a larger air filter but retain a stock-like appearance. The Dinan 330 intake cover seals better to the lower section ensuring no power-robbing hot air enters the intake. A new lower tube draws air from the brake duct, nearly doubling the volume of cool air entering the engine.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

Upgrade your BMW's air filtration system with the Turner Motorsport Exact-Fit High Flow Dry Air Filter. This direct replacement for your factory air filter offers superior airflow, allowing your engine to breathe better and enhancing both power and fuel economy. Enjoy immediate performance gains with this reusable filter, which outperforms stock paper filters and requires minimal maintenance.

Key Benefits:

  • Improves engine breathing for better performance
  • Enhances power throughout the power band
  • Increases fuel economy
  • Reusable filter for long-term savings
  • Easy installation as a direct OEM replacement

Oiled versus Dry Filters:

Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters do allow slightly better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards. This filter will save you money by no longer needing to replace a paper filter.

Dry filters offer slightly lower airflow but are easier to maintain while still outperforming the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.

Both dry and oiled filters flow better than stock and can be reused.

Maxiumum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

aFe has reported gains as high as 6 hp and 12 lb/ft torque

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

This aFe intake fits the following BMWs:
1999-2006 E46 BMW 323i 323ci 328i 328ci 330i 330ci 330xi
2001-2006 E46 BMW 325i 325ci 325xi - Only with M54 Engine - Not for SULEV M56 engine

Bespoke. A word that perfectly encapsulates the mindset of Eventuri. Performance parts with obsessive attention to detail and an unyielding dedication to quality. Perfectly designed to maximize the potential of each individual vehicle and meticulously refined through rigorous testing. Eventuri offers a product that stands in a class of its own and delivers outstanding power increases without making false claims or exaggerating dyno numbers. With patented designs such as a custom velocity stack filter housing and improved ducting that guides the flow of air into the engine, to the breathtaking uniformity of the weave pattern. These are performance products for the truly discerning customer. When it comes to styling a vehicle the proper look is one that complements, not cheapens the inherent design. Race-inspired carbon fiber completes the look and style of every BMW M-powered model and Eventuri delivers on an entirely new level. Performance increase = 10-15hp, 8-12ft-lb The E46 M3 intake system is a result of extensive data logging, dyno testing, and design optimization. The aim was to develop an intake system for the S54 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience. The E46 M3 Eventuri system uses a Patent Pending Carbon fiber Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design that invokes the Venturi affect. Made from 100% prepreg carbon fiber of the highest quality, the workmanship on the housing is second to none. This encapsulates the filter and is mated to an anodized aluminum inlet cowl to ensure a smooth inlet flow path. The filter itself is a deep pleated, high flow double-cone configuration that is dry to avoid damaging the MAF sensor. Finally, the assembly is then mated to an aluminum heat shield which effectively shrouds the intake from engine bay heat and captures the ambient air being diverted from the scoop. Also, notice the rubber spacer on the mount of the heat shield - this is for the headlight module to sit on so that it remains at the right height - small details are important! 100% Prepreg carbon fibre with a CNC machined collar - the air scoop forces ambient air directly into the filter opening. This scoop simply clicks into place in the front right-hand brake duct and effectively saturates the mouth of the intake with cold air. It has been designed to take up half the height of the duct in order to allow airflow to still continue through the duct for the brakes. The scoop is so effective that even after a hard drive, the aluminum cowl at the mouth of the intake will still feel cold to touch! Each kit consists of: 100% Prepreg Carbon Fibre Intake Housing Anodised Aluminium inlet cowling High Flow Filter CNC Machined MAF tube 100% Prepreg Carbon Fibre Air Scoop with CNC machined aluminum collar 3 Aluminum heat shields with neoprene lining High-quality Silicon coupler with BMW specification hose clamps This kit fits the following BMWs: ​2001 - 2006 E46 M3

We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future.
