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 Topkick vehicle manufacturers equip cars with intakes that bring air inside to the GMC Topkick engine directly. GMC Topkick Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the GMC Topkick 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 Topkick 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 Topkick Cold air has more oxygen, for instance, so GMC Topkick cold air intakes have become popular GMC Topkick intake upgrades. Other upgrade types focus more on greater GMC Topkick air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded GMC Topkick air intake system in your car.

Was ify after reading some things in forums about this site. But it was a very good buying experience. tje exhaust sounds great and really simple to install other than the pressed bolts on the first flange. shipping took a week.
