Even among the many first-class aftermarket intake manufacturers operating today, Injen stands out with its competitive grade 2007-2013 and 2014-2017 intake components, which can be tested at the Pomona raceway just a few miles from this US company. Their components are mostly CARB-compliant, though California residents still need to apply for a CARB decal. Injen’s 2007-2013 cold air intakes often come in a choice of a polished or a wrinkle black finish on the tube to match the under-hood look your prefer. Made out of mandrel-bent 6061 aluminum with a washable and reusable filter, the company’s 2014-2017 cold air intakes are covered by a limited lifetime warranty and are made entirely in the USA. American Trucks is an authorized dealer so you can be sure that your Injen intake is the real deal, and not a knockoff part.
