AEM Cold Air Intake Systems

AEM Cold Air Intake Systems replace your stock airbox and air filter so your engine can get cooler air from outside resulting in better performance. Cold air is denser than the hot air trapped inside your engine compartment and contains more oxygen which allows your engine to burn more fuel cleanly and efficiently.

Every AEM Cold Air Intake System uses a specially designed inlet pipe that relocates the included high performance AEM Dryflow Air Filter away from your hot engine and moves more air into your engine. AEM also finely tunes each cold air intake system to make sure it doesn’t cause lean air/fuel ratios or check engine lights.

AEM Dryflow Air Filters can last up to 100,000 miles in normal driving conditions before requiring any cleaning. It’s also very easy to clean and doesn’t require any air filter oil after washing.
