K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

My wife has a 2002 BMW z3 and since easily fitting new K&N air filter 33-2070, the car is excellarating faster and smoother, rumble from engine sounds better. It's a 2.2 strait 6, so I bought one for my S type Jag, same results. I highly recommend this product and delivery, Allan.

Have filters, now, for our old 1987 F250 Ford truck, our old 1987 Mecedes Benz 300TD Diesel wagon and our 1996 BMW Z3.
We're happy with all three filters (so far...).

Quality product, fair price, and quick delivery made this purchase a win win. I love driving a BMW and I love not paying the dealer to change my oil. I will be ordering again.
