BMW Intake Parts for BMW 5 Series E39 (1996-2003)

BMW E39 M62 4" Silicone Intake Boot is engineered to enhance air flow and performance compared to the factory corrugated rubber boot. Designed by Turner Motorsport, this intake boot features smooth contours and stepped flanges to ensure a seamless transition from the air box to the throttle body. The single-piece construction simplifies installation, offering a straightforward replacement for the stock two-piece design.

• Improved Air Flow: Smooth contours enhance air flow compared to the OE corrugated rubber boot.
• Seamless Transition: Stepped flanges maintain a smooth internal diameter transition.
• Simplified Installation: One-piece design makes installation quick and easy.
• Durable Construction: Made from 5-ply reinforced silicone for enhanced durability and performance.
• Enhanced Resistance: Offers reduced thermal conductivity and superior resistance to ozone and UV degradation.

The stock rubber intake boot often fails due to its accordion section, leading to vacuum leaks, rough idle, and increased fuel consumption. Upgrading to the Turner Motorsport silicone intake boot will eliminate these issues and improve overall performance.

NOTE: This boot is a direct fit for the M62Tu (9/1998+). It will fit the non-TU (pre-9/1998) models with a slight relocation of the MAF sensor.

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. 

This item fits the following BMWs:

E46 325i 325xi 330i 330xi

Introduced in the late 1990s, the DISA (Differenzierte Sauganlage or differentiated intake system) valve plays a crucial role in adjusting the intake manifold's effective length. This mechanism incorporates a flap that opens and closes in response to DME inputs, optimizing airflow for both high and low RPM use.

Although the DISA system marked a significant leap in engine efficiency, it has become a common point of failure in older BMW models. The flap is secured to the body using a plastic pin, prone to degradation over time due to heat exposure. A malfunctioning DISA valve can lead to various issues, ranging from power loss to severe engine damage.

Signs of DISA valve failure include:

Audible rattling from the upper intake manifold. Power loss during different RPM/load conditions. Decreased fuel efficiency due to improper flap operation or valve failure. Illuminated SES/Service Engine Soon light, indicating lean/rich conditions or misfires (common DTCs include: P1083, P1084, P1347, P1348). Potential valvetrain damage as a result of flap pin failure, leading to plastic and metal debris circulating in the engine. If you notice any of these symptoms, it's crucial to replace the DISA valve promptly to avoid further engine complications. Continued use with a faulty DISA valve can escalate to extensive engine repairs or replacement.

Fortunately, Febi-Bilstein offers a high-quality OE DISA valve designed for seamless integration, ensuring optimal fit, finish, and functionality. Installing this valve is straightforward, requiring basic hand tools and less than an hour of your time. Restore your engine's performance and safeguard against major damage by upgrading to a new DISA valve from Febi-Bilstein.

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes.

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.

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. 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.
