BMW Intake Parts for BMW Z Series E85/6 (2003-2008)

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.

Eventuri was founded by true enthusiasts who had a shared passion for cars and performance, engineers that had a background in Aeronautics as well as automotive tuning. After experiencing disappointment time and time again from the claims set forth by the automotive aftermarket, they set out to raise the bar. Their goal? Set a new benchmark for intake design providing true gains, not just "claims."

Designed to use the "venturi effect," Eventuri has created a unique intake system that out-performs the competition. The Venturi effect is when the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. This means more air-flow and smoother delivery, resulting in more power. But that isn't all that sets their design apart. They also use an inverted cone filter that is decoupled from the MAF. This is done because it means the filter no longer dictates the shape of air-flow, thus creating the venturi effect. 

Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dyno testing. They strive to publish all the development information to illustrate the depths they go in bringing an intake from concept to reality. Also assuring to only use the highest quality components for style and durability
