One of the most crucial elements to maintaining a healthy engine is airflow. Your engine needs air to make power, and the cooler the air flowing into it, the happier it is. Stock airboxes are often restrictive, causing the engine to work harder to pull in fresh air. The main principle behind a cold-air-intake system is to not only lower the air temperature flowing into the engine, but provide a greater volume of flow, thereby increasing power. Most of these kits require little installation time and can be put on with a few basic handtools. Here is a list of some of the latest cold-air intakes on the market that are sure to give your engine a little boost.

The new intake delivers a more streamline flow of air to the engine more efficiently.
