'Junk Science' is an equally applicable term when you use anecdotal evidence to say the K&N *increases* engine wear.
Honestly guys, if they were that bad, nobody would go near them!
I think they fit into the category of a cheap owner fitted mod. Because of this, every man and his dog has an opinion on how good they are/how useless they are: it's easy to comment.
I use one and have zero complaints. I've always used them, even before I started thinking Bruce Anderson has the last word on engine mods. Anyone here read David Vizzard?
The 'K&N' filters are many and varied. The only thing they all have in common is the filter material, and this has been proven to filter and flow effectively on countless occasions and tests. Serves you right if you try to slap some wierd looking pod on your motor and claim the K&N is useless. It's not exactly rocket science.
