An internal combustion engine uses oxygen just as fires require oxygen to keep aflame. There is no internal oxygen tank in a car for this purpose, as that wouldn’t be very efficient. Instead, GMC Sierra vehicle manufacturers equip cars with intakes that bring air inside to the GMC Sierra engine directly. GMC Sierra Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the GMC Sierra car all the way to the engine, though stock versions aren’t always the most effective.
For that reason, many car owners turn to aftermarket GMC Sierra air intakes to increase the effectiveness and efficiency of their vehicles’ intake capacity. The greater the amount of oxygen supplied to the engine, the more power it can produce. GMC Sierra Cold air has more oxygen, for instance, so GMC Sierra cold air intakes have become popular GMC Sierra intake upgrades. Other upgrade types focus more on greater GMC Sierra air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded GMC Sierra air intake system in your car.

The exhaust sound really good. Installation is straight forward. Thanks

I would have rated these a 5 if it were not for the fact that they needed some additional sealant around the lens. Luckily I had some left over rubber sealant lying around - I'd read about and experienced this before with my other aftermarket lights. Overall I am very satisfied with the product and the customer service. I was notified of a short backorder (about a week) shortly after placing my order, which happens from time to time. Wes kept me updated and called me as soon as the item left. Great guys to deal with!
very good quality spoiler - body shop said it was easy to put on. I will order my body kit and hood soon! THX
