I bought this filter for my brothers 328i BMW and just like every other K&N filter I've purchased, it's solid. The Germans recommend changing the oil every 10,000 miles and so this filter is perfect. After changing the oil and installing the filter, the car rides smooth. Thanks I've been a customer for a while and you will continue to have my support.

Fits better than stock filter. Definitely noticed more power and slight increase in throttle response on my turbocharged BMW 335i. Faster spool up and noticeably harder pulls under full throttle. I've been using K&N filters on my turbocharged cars for 15 years, always with the same results. Best performance filters on the market.

Just purchased a K&N drop-in air filter for my 07 BMW 335i and I am very pleased with the results. It gave my exhaust a throaty-er sound and helped with acceleration too just like K&N claims. Overall it is a great product at a great price.
