Air Intake

[Speeddemon13]

What is the difference between the k&n 77 series, 63 series and the aircharger? which one should i get for my tundra, i dont mind the extra noise when you get on it or anything and i kind of like the chromel look under the hood

I think one is for off-road use and not 50 state legal.IMO I would go with a sealed intake.Good luck maybe someone that has experience with both will chime in.To me K&N just don't filter well enough I use to be a die hard fan until I had their drop-in filter in my tundra for about 5k miles until I purchased my true flow intake and the gunk build up in the throttle body was unreal.Looked like the truck had 40k miles or more on it.I cleaned out installed new intake and now when I check it its clean as a whistle.
