Have you noticed that your engine seems to perform better in cooler weather than it does in hot, humid weather? You may think this is because it is harder for your engine to cool down, but the truth is that cooler air has more oxygen, and the more oxygen your cylinders receive, the more power your engine is able to generate. This is the concept behind the GMC K3500 cold air intake system, which is designed to increase your engine’s oxygen supply and give you more power, more torque, and better fuel efficiency. Your engine’s stock intake system routes the hot air in your engine bay to your cylinders, which is a sufficient supply, but far from optimal.

The K3500 cold air intake system brings in cool, oxygen-rich outside air. In addition, the GMC K3500 cold air intake system comes with a high-flow performance air filter that allows a greater quantity of air in to your cylinders.

Not only does the K3500 cold air intake system give you a horsepower increase of up to 15 percent or more, but it also saves you money. Greater fuel efficiency means less money spent at the gas pumps, and a washable, reusable performance air filter means you may never have to buy another paper air filter again. To install your GMC K3500 cold air intake system, you simply remove some of your stock factory plumbing and drop the system in place, replace your paper filter with the high-flow filter, and you are ready to enjoy more power from your engine.We carry a full line of K3500 cold air intake systems in our extensive online catalogue, along with thousands of high-quality discount auto parts and accessories.
