    This is the best setup for an air intake gives you increased throttle response and makes your motor way happier receiving lots of clean air

    Ordered the blue donaldson, along with a billet wheel, sounds much better, filters better and looks much cleaner! Very happy!

    Nice kit, easy install.

    I received my kit yesterday, and installed it right after work. It took about an hour. But that included removing the air box and battery box. Completely removed air box, and trimmed the tabs on the battery box.
    Made a difference driving to work today. Slightly louder on the hills, but not on the level. I have the Blue filter.

    I'm still in shock how much this changed my truck, it's it was like going from a carburated 6cyl to a fi v8. My truck lurches forward from stop lights instead of crawling. I towed our 5th wheel to the lake the week before the install and usually kept it floored going up the hills, the week after I put this in I pulled the 5th wheel to the same spot and had to use almost half the trottle as before, found myself above the speed limit going up the hills. If you are on the fence don't stay there!

    Bought this for my Early 99 and installed with tuner and pyro gauge.
    Great Fit with no increase in noise level. Thanks Riffraff
