I tossed the kn I had in there because I been reading nothing but bad on hear about it. So I decided to change to a napa gold. Its the rigid plastic lined white fuzzy type filter. Are these a good quality filter. I also was on rock auto today and noticed they sell ones by pronto. Hastings. fram extra guards.wix and mahle. All those filters are around 7 to 8 bucks except the mahle which was around 14 bucks. The napa gold I put in was I believe 15 bucks. Hopefully the napa golds a good one.
