K&N 33-2328 Air Filter Product Reviews

Wednesday, March 29, 2017 - Part 33-2328
Installed it on my '09 Volvo XC90 V8 R-Type. The previous OEM filter was only replaced 13,000 miles ago. But since I do my own routine maintenance I figured I can save more time and money by installing a non-disposable filter and rated at 50,000 miles between cleaning. Oh boy was I in for a pleasant surprise. Right off the bat felt smoother acceleration from stop and when on the move. I bought my car low miles at 45,000 for being over 7 years old and have replaced the filters twice with disposable filters. I thought at times there were issues with my fuel system or freezing winter temperatures because of jerky acceleration sometimes. In the 2 weeks since I installed the filter, none of those have happened even on cold winter mornings. I did not put my car on a dyno but I have a pretty good feel of the smoother acceleration. The engine sounds quieter, perhaps it can breathe perfectly now. Disposable filter cost between $25 to $45 online, so this is an amazing $65 investment
