Let your engine breathe better by replacing your boring factory air filter with our K&N Intake! Replacing your BMW's intake is a crucial component to change with modifying your BMW with performance in mind. It is a great compliment to an exhaust system, but will also improve your car's performance on its own. Performance gains vary from vehicle to vehicle but a noticeable audible “growl” by the intakes’ open concept is evident as well as the smoother acceleration across the power band.
About the K&N BMW Intakes
The Generation II FIPK® is K&N's ultimate performance product, designed to increase power by as much as 10%. Most FIPK's are street legal in all 50 US states and come with a Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available.
Which Series Will I Recieve?
K&N provides a 57-Series and 63-Series intake for each BMW 3 Series model. Due to varying stock conditions, when you order, we will ship out whichever intake will allow us to get it to you the fastest. These intakes are identical with the same HP gains, specs, and price. Therefore, we have combined them here into this one product to eliminate confusion.

“We used what BMW designed and made the intake better,” said K&N Performance Kit Manager Bert Heck. “We incorporated the factory fresh air inlet for more power.”
