No more slow starts! Does your car feel old? Age may not be the issue at all, your throttle cable bushings are mostly likely worn out and your car has lost its pep!

Your throttle cable is the main connection you have from the gas pedal to the throttle body. Do you have hesitation or delayed pedal response? Think of when you are sitting at a stop light or making a turn into a flow of traffic, you may not realize it but if you haven't replaced your throttle cable and bushings this will require you to apply pressure to the gas pedal before getting feedback which can cause slow starts at stop lights and put you in danger when merging in traffic. These are not issues with old cars, they are issues related to your throttle response!

Symptoms to look for: lackluster/sloppy throttle actuation, deformed throttle cable appearance, and bushing condition. Your throttle cable bushings can be soft, cracked or even disintegrated by now.

Upgrade from failed rubber to new billet aluminum bushings for quick gas pedal response and a better engagement with your car.

Since 1999, aFe (Advanced FLOW Engineering) has been developing and manufacturing high quality accessories in their facility in Corona, California. Starting with air filters and intake systems, and now expanding into exhaust systems, suspension components, tuning modules, and more, aFe products are a great way to improve the performance of your BMW without altering its fundamental character. Owned by a BMW enthusiast, aFe power is recognized the world over as a leader in quality performance products for your BMW.

• Constructed with 100% polyurethane
• Five layers of progressively finer mesh cotton gauze media
• Washable and reusable for multiple cleaning cycles
• Excellent dust-holding capacity for a longer service cycle between cleanings
• Integrated urethane bump seal insures a tight, no leak seal
• Outflows stock paper filter for improved horsepower and torque

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:
E30 M3 (1988-1991)
E30 318i (1984-1985)
E28 528e (1984-1985) and 535i/535is (1985-1988)
E12 5 series, All (1975-1981) - including 528i, 530i, 533i
E23 7 series, All except 745i (1977-1987) - including 730i, 733i, 735i, L7
E24 6 series, All except M6 (1976-1989) - incl. 630CS, 633Csi, 635CSi


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.
