K&N 33-2990 Air Filter Product Reviews

Tuesday, April 3, 2018 - Part 33-2990
Works as promised. I have used for years on my previous cars and have still continue to live up to its name. My gas mileage has improved and my driving style has remained the same. Before it was using 10.3/100km now its down to 9.1/100 . Same drive route and style. Worth the money.

This replacement didn’t improve the performance, only a little bit more turbo noise. In case of fuel economy, I don’t know because when I replace it the car only had 80km. The car is BMW 116d It’s making 5.5l/100km Reason: all the cars that I had, I always used K&N air filters and It improves fuel efficiency and nice intake noise
