I have an 07 F-150 XLT 5.4L and read really great reviews about the K&N 63-2556 Charger intake kit on the site I ordered it from. I have read another post, here, that stated these will run the increased risk of wearing out pistons and valves, does anyone have experiance with these intakes. I'm also seriously looking at the gryphon tuner, but will this combo benefit me, this is basically an everyday driver that I occasionally play in snow banks and mud puddles with. Thanks for everyones help, I'm really new to mods.

 

Yes... a good combo, you will be amazed what you truck can really do.

 

Once again thanks man.
