I would not use the Monster Flow.
I dyno'ed it at 3 HP LESS than a factory filter.
A foam air needs something like twice the surface area to flow the SAME amount of air as a paper or cotton filter. 3 HP is in the range of Dyno error, but still it's not a gain by any account.
But if your heart is set on one, I will sell you mine for $75 bucks.
Right know I just use it as a spare when I'm cleaning my KKM. That way I don't have to be without my car while the KKM is drying after I clean it.
