One more tid-bit.
Ever notice when cleaning a dirty K&N, it's only dirty on the end from the small opening in the housing on the end. I opened it up sideways with a diamond shape and now when I clean it, it shows the air is actually getting down the sides of the filter too and just not hitting the end of filter.
I know, I know, some of you don't like opening the air box. I up'ed the slow jets one size too and she runs great this way.
