I've used K&N's for years, I'm literally across the freeway from
their plant here in Riverside CA. A friend of mine is sponsosred by
them, he's doing R&D on a Ford Focus for them. Drag races it.
I think you may have been beat up by a K&N or something Dave, the way
you're so against them. They're a fine product and they work
extremely well.
I know a lot of people claim to have special knowledge, but you can't
argue with experience. I have got 20 K plus on my KLR with a K&N
filter, 80k on my 5.0 Mustang, 80k on my last Dodge, 10k on this one,
etc.etc. All totalled, I'd guess I have about 285,000 miles on K&N's,
never had to rebore anything.
K&Ns do flow better than paper filters of the same size. That said, I
prefer foam filter for my race bike (XR650-R), less sensitive to dirt
saturation.
Why are you so anti K&N?
You even go so far as to insult people's intelligence that owns them!
Come on man!
