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.

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.

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.
