How much HP should I see?

[GDT]

How much HP should I gain from just a K&N pnl filter for my 3.2? & Should the gain be noticeable when i drive it? Should I be able to notice the fuel savings as well?

i don't think you will get any gains except for your butt dyno and some "breathing" noises if you are lucky.

it's only a filter but it should be better then the oem one, although arguable... just install it and be happy =) or if you want install a full intake

Max like +1 or so. Maybe invest in an intake such as the EvoMS one. Solid piece and product
