Looks great and is easy to attach.

Previously used by K&N on another truck. I bought this for my '04 Silverado with 5.3l v8. Fits perfectly and was very easy to assemble. I suggest moving the two hoses that run over the pipe underneath so they don't rub. All you have to do is loosen and twist the clamp on the radiator and coolant reservoir to fit underneath.

Pros
  • Pleasant to use
Cons
  • Some nuances

2002 Silverado 1500HD 6.0L

Easy install, mounting the boot at a 90 degree angle to the throttle body wasn't great. I had to reuse a factory female adapter to connect the 90 to the throttle body. The 90* clamp on the metal pipe didn't hold up well either. Looks good and sounds good, but too expensive. Be careful, there isn't much clearance between the 90* and the fan cover, and if you add a throttle body gasket the boot will rest against the fan cover.

  • Best of the Bunch

Small warning

I really like this purchase, not only did it add the promised throttle response but it looks great under the hood. The only reason for the headline is that my pickup (99 Silverado ext cab 4.8L) had a gapping problem with the rubber knee after adding a silver ball afe (throttle body gasket). The elbow rests a bit on the fan cover, which is a bit of a concern, but so far the air intake has been running without damage for about 4 months. Great purchase, just do your research before making aโ€ฆ

Pros
  • Good product for the price
Cons
  • Periodicity

Totally worth the money

I was skeptical about buying an item that 'claims' better performance and fuel economy, but I was wrong. I recently picked up my 2004 Chevy Silverado 4x4 and put 33" tires on it and lost about 1.5mpg. After installing a cold air intake I got that 1.5mpg back! on gas, but otherwise it sounds the same. When comparing an aluminum tube with a plastic tube, I could not find a single advantage. I went with aluminum tubing due to extreme temperature swings and thought it would hold up better thanโ€ฆ
