ChadC Posted October 13, 2013 Share Posted October 13, 2013 well crap I have used K and N for 10+ years because of the quality. They always went above OEM needs for a filter. Steel base, nice spring for High flow Oil bypass, nice filter medium, and a good quality build. ..not any more. USA MADE steel base Mexico stamped metal. less strength for pressure (suspect that is why there are more holes) the cage is differentUSA MEXICO yep made in MEXICO not my filter but from the Interwebs The new anti drain back valve is easy to press and open, but has relatively small passages for oil flow. :-( its on the car now, but i Will no longer be buying K and N products any more. bummer...

Jon Posted October 20, 2013 Share Posted October 20, 2013 Here's a list taking price out of the grade sheet: Link to comment Share on other sites More sharing options...
C4in mesa Posted November 1, 2013 Share Posted November 1, 2013 I cringed when I read this thread ! I have always used K&N oil filters and I use their washable air filter. I had ordered a oil filter about 2 months ago off ebay. K&N 2002HP for $11.28 delivered to my door off ebay. I remembered finally that I had read this thread and went out into the garage and found the filter on a shelf. Made in the U.S.A. I ordered another one just a minute ago to see if it turns out to be a made in Mexico filter. God only knows how many of these filters are sitting in a warehouse for my L98 motor ? Ten's of thousands nationwide gathering dust ? I can't beat the price thats for sure. The next time I am in AutoZone I am gonna go check out the K&N oil filters and see where they are made. P.S. the last time I was in AutoZone I bought a 5qt jug of Castrol 20W-50 oil for $28. Then I went to Walmart later that day and found it for $18. Good thing I saved my receipt. The guy said to me at the check out when I returned it I could have told you it was cheaper at Walmart. But it's not their policy to point that out !

Shifty Posted November 1, 2013 Share Posted November 1, 2013 What I find really amusing about that list is teh different grades they give Wix and teh Napa filter, which are one and teh same... Link to comment Share on other sites More sharing options...
Unreal Posted November 1, 2013 Share Posted November 1, 2013 So they changed the design, I don't see any data showing the mexico filters are worse. For all we know the new design is better than before. Link to comment Share on other sites More sharing options...

For all we know the new design is better than before...yes because products once made here in the USA that are now made in Mexico have a long history of outstanding quality please I'm transferring a bunch of products to Mexico right. I guarantee the quality will be just as good or better than when it is made here in Tempe. I've done a few Mexico transfers and I find that it gives the opportunity to implement improvements that may not have been viable in the US. Without any data on the new filter there is no way to know if it is better or worse. Link to comment Share on other sites More sharing options...
