I have used this product in all my cars and ATV over the years. 5 Star product. But I wish I would have thought it through and bought the cold air induction for my new Chevy.

Arrived on time in perfect condition. Easy to replace on my 2000 GMC. Make sure to vacume out the filter box. Seems to have a bit more pep off the line. Haven't driven far enough to check fuel milage yet.

Fit perfectly. Throttle response is quicker, seems to really open up the engine.
