All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).

This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -

powedercoat chargepipe ECS Tuning blow-off valve Includes three interchangeable BOV springs, allowing you to tailor venting function to your existing modifications. 1.9 (For use with factory software) 2.0 (Pre-installed in the SQV BOV - suitable for stock or "Stage One" software) 2.2 (Suitable for "Stage Two" software) vacuum plugs for the stock diverter valve hoses silicone hose connection to intercooler piping all hardware and hose clamps with instructions

When it comes time to change your spark plugs, you may wonder about colder stepped spark plugs as many others have. Colder spark plugs work by pulling more heat out of the engine's cylinders (making them "colder") and dissipating it into the engine's head, which is then cooled by the cooling system. Depending on how you have your engine built, these could be a great addition! Colder plugs can help prevent engine knock and prevent the tip of the spark plug from melting or misfiring. There are two rules that most people tend to go by when deciding on which spark plugs to buy: The first rule of thumb is that with every 100 horsepower added, you should run spark plugs that are a step colder than your stock plugs. This is generally accepted across the motorsports community but unfortunately isn't always the most accurate measurement of when you will need colder plugs. The second rule is to go a step colder any time you massively alter cylinder temperatures by adding forced induction to an NA engine, by increasing compression ratio, after altering timing in a major way, or by changing fuel types to something with a higher octane rating such as racing fuel. Adding spark plugs that are a step colder outside of these conditions, with no real change to the engine, can actually hurt more than help by leading to spark plugs fouling quicker than normal and by making the car harder to start in cold weather conditions. We suggest talking to your engine builder or tuner before making the change, or you can call our Turner Motorsport sales staff to discuss what modifications have been made to your vehicle and see if these plugs are right for you!

When upgrading your turbos or increasing your BMW's power potential, it's important not to overlook your fuel pump. Both low and high-pressure fuel pumps can only flow so much fuel, limiting power potential regardless of turbo size or other power adders, especially when running an ethanol blend. Upgrade your BMW fuel pump with Precision Raceworks' Low-Pressure Bucketed Fuel Pump Kits. Precision's low-pressure fuel pumps are designed to flow significantly more fuel than your BMW's stock system, ideal for customers who are upgrading their vehicles or plan to run blended fuel or E85 alone! This is a true plug-and-play solution that anyone can install in their home garage and start taking advantage of the benefits right away. Precision Raceworks' Stage 2 bucketed fuel pump kit includes a genuine Walbro 450 (F90000274) fuel pump, capable of supporting up to 575whp on 93 octane pump gas or 500whp on 100% E85! In order to prevent having to send in your fuel pump, each of Precision Raceworks' kits includes thorough instructions and all of the items required to assemble your kit at home. This prevents delays in shipping, potential damage to your stock fuel pump housing, and reduces assembly costs to keep prices low. It also improves installation as there is no guesswork on engagement and sealing of o-ring or complications and risks of tightening clamps that can poke holes in critical plastic components nearby. While all bucketless fuel pumps flow .2gpm more than a bucket design that retains the venturi, it comes at a cost. Bucketless pumps should not be driven on tanks lower than 1/4 full and should not be used for road course racing. This is not a disadvantage of only bucketless designs, but also a disadvantage for any bucket design which deletes the venturi. If you do not plan on road course or drag racing (not street racing) and are responsible at maintaining 1/4 tank of fuel during spirited driving, bucketless pumps can be a cheaper alternative for you.

Rid your BMW's N54 of misfires, sluggish throttle response, rough idle, and power loss with Precision Raceworks' High-Performance Ignition Kit! Precision Raceworks' ignition kit is designed to fit any vehicle with an N54 engine and offers the highest output of any kit on the market! Featuring 100% Plug-&-Play connections, low resistance 50ohm/ft proprietary plug wires, and design technology from Marine and Aerospace applications, these coils are guaranteed to output consistent high voltage and current for optimal ignition system performance and reliability. Every component in this kit meets or exceeds OEM quality and features premium seals for dust and water resistance. While coils do not directly increase horsepower, stock BMW coils can wear out quickly, resulting in underperforming voltage and current output. This often leads to weaker spark intensity and reduced power output. Due to the increased voltage and current output, many customers have seen as much as 20+ whp/wtq gained by switching to Precision Raceworks coils over all other coils on the market! By upgrading to Precision's Performance Ignition Kit, spark quality can be restored and lost power regained, often with the additional power beyond what other coils provide. No software tune is required for installation or operation, but if desired, coil output can be increased to 118mJ from most software tuning companies!

The OEM plastic Positive Crankcase Ventilation (PCV) valve does not hold pressure well, even when brand new. This means that when you are in boost conditions, the highly pressurized PCV valve leaks charged air back into the crankcase. Depending on the condition of your PCV valve, this can range from irritating to dangerous. Additionally, if your valve cover is cracked, loose, or has a bad gasket, you are likely experiencing a pressure leak either internally or externally, as well as potential oil loss issues. ECS Tuning now offers a solid aluminum PCV valve upgrade designed to address these issues by preventing leaks and outlasting the standard BMW-designed PCV! The internal components of this aluminum PCV valve fit tighter than the OE design and can withstand significantly more abuse, perfect for high mileage N54s, N54s that have been tuned, or N54s with upgraded turbos (larger twin or big single turbo builds). This may not be your last PCV Valve, but it will certainly outlast both the Genuine BMW and other common aftermarket alternatives!
