K&N E-2232 Air Filter Product Reviews

Monday, August 21, 2017 - Part E-2232
I change my air filter by the K&N air filter. In fact, the previous owner of my car (BMW 318i E46) bought an air filter from the mark Green. The dimensions of Green's filter was big compare to the K&N's filter. I had some difficulty to put the Green's filter in the air filter box. But with the K&N which thiner, can mount the filter without difficulty. Moreover, the K&N's filter need to be washed every 50 000 Km, while the green's filter need to be washed every 8 000 Km. This why I choose it. Finally, the sound is better.

Fitted this today to my BMW, really nice and simple to install. Increases power as suggested by K&N and I'm really happy with the product. :)
