Just bought the K&N today. Haven't installed it yet. Got it at Pep Boys and they're currently running an off of 25% of anything over 100$. Originally 275, brought it down to 225 out the door.
I believe it said 10-12 hp and 1.5 mpg "gain"Not bad...
You know what hp gain and mpg gain you get with it?
IF you were to lose the 4.7L engine hat and flexible intake hose I would agree with the above 100%. As is the K&N is a heat saturated noise maker, but the OEM causes turbulence and back pressure in the name of noise reduction.for the best HP gain leave the factory Cold Air Intake system in place and leave the aftermarket Hot Air Conversion on the vendors shelf
you will lose HP for sure, all you get is induction noise (which sounds nice and make you think you are going faster) but feeds the engine Hot Air from under th hood and you lose dude .......

Yup should be Gen IVshould move this to the appropriate gen sub forum.
