All internal combustion engines are powered by a mixture of gas and air. The O2 comes in through the intake system and passes through the filter before it combines with fuel in the combustion chamber. The more clean air that is available at any given time, the better your Jeep Wrangler will perform. Fuel economy and power of your Jeep Wrangler can be improved by simply adding a new air intake system and air filter. Both parts are relatively inexpensive and easy to install. But while intake systems are permanent devices, filters should be replaced every twenty to thirty thousand miles. We offer a wide selection of air filters in various shapes and sizes. Each is designed to fit specific Jeep Wrangler models.
