Looking to put a K&N Air filter on our Mustang. Anybody have thoughts??
yeah, I was looking at the 3 runs, and they really are really close.That's messed up to lose power, if tests weren't rigged.
+1 just ran one for about 6 months and was very disappointed, back to paper and couldn't be happierI used to run them on everything. Now I won't run one. They flow more because they allow more to pass through the filter, and the oil can screw up your MAF. I'll only run a paper filter in everything from now.
