The K&N debate is like a religious argument - there are folks on each side, and they all seem to feel strongly about it.

My experience with the K&N is not Hummer related, but I have two Land Rover Discovery II's; I currently have a K&N in one (because the previous owner had installed it), and an OEM paper filter in the other. I see absolutely NO perceivable performance gains from the K&N.

I personally prefer the OEM filter over the claims of performance gains at the expense of potential excessive long-term wear. To me it is simple - if you are letting more air through than the OEM filter, you are also letting more of other stuff through, too.

I have no plans to puta K&Nin the Hummer.

 

Thanks much for the insight guys!
Before making this post I heard more H1 folks 'against' K&N than 'for'. For that very 'letting more other stuff through' arguement. You guys have reinforced that position. I'll believe I'll bechanging to an OEM filter sooner rather than later.
