K&N 57-1516

Where do I buy K&N 57-1516 Fuel Injection Performance Kit Gen2 Air Intake Kit Extra HP, Extra Sounds, and a Little Extra MPGBy S. BrooksI bought this primarily to try and get a little more gas mileage from my Dakota Quadcab. It accomplished that - I get 1 - 2 mpg better than before. I can definitely tell it increased my acceleration (which is nice, but makes it hard to get that extra mpg :-)I knew to expect some additional noise/sound under acceleration, but wasn't sure of the extent. It is substantial at certain rpms ! When cruising or coasting - no additional sound level, so that's all good. At certain rpms under 3/4 to full throttle - it is extremely loud. I like the sound for the most part (I love listening to all kinds of fast cars with good exhaust tones anyway...). But if I could snap a finger - I'd tone the volume down just a tad.All in all - it's worth the money I paid and installation wasn't too big a deal.See all 4 customer reviews... » More Information about K&N 57-1516 Fuel Injection Performance Kit Gen2 Air Intake Kit.
