K&N E-2022 Air Filter Product Reviews

Encaja perfectamente en Bmw 330i del 2008 con motor n53b30. Se nota mejoría al subir de revoluciones con un sonido más agradable. El envío me vino sin pegatinas, una lástima.

After fitting this filter, I could feel the few extra HP right away. The engine sounds slightly better and it revs a bit faster. Great product.

Excellent filter as with other K&N's used in the past and a noticeable difference in the car's performance. Lasts the vehicle's lifetime too, so highly recommended for both reasons.
