K&N 33-2452 Air Filter Product Reviews

Thursday, August 25, 2016 - Part 33-2452
This filter eliminated the throttle lag in 2nd gear and gave my F-sport a much more linear acceleration. I can't say anything about more power, but it feels much better when I drive hard. Definitely a noticeable difference.

In my opinion, these filters are a must in any car or truck. Made a noticeable difference in a Lexus GS-350
