K&N Air Filter 2006 Crew Cab 4.8

The best 49$ ive spent. WHAT A HUGE NOTICABLE differance on acceleration and petal responce. Ive always felt like my truck was sluggish and a little boggy. It feels like it has life in it now. Im very much impressed. I was wanting a airraid or cool air intake by K&N but could not afford that. I would highly suggest the replacement. I wonder if I will notice a differance in MPG

Wow, I have the full K&N CAI on mine and I can't tell one bit of difference other than the noise. Just goes too show that every vehicle has it's own personality. Glad to hear you got your money's worth.

I heard that CAI increases throttle response a bit because of the long pipe. I wonder if those tornadoes work that they use to show on tv

Now just get the airraid tube and you'll be set. I see no performance gains or mileage gains from my CAI. Just makes alot of growling noise under moderate to heavy throttle. Possibly a difference if I changed my muffler but as a stand alone upgrade it was alot of wasted money.
