Injen Authorized Dealer

Injen MR Technology maximizes horsepower/torque gains while at the same time stabilizing air/fuel ratios. MR Technology and other Injen technologies tune the intake system, making it the FIRST TUNED INTAKE IN THE WORLD!

Injen's short ram intake is a traditional, underhood intake system that is placed in the stock location of the factory air-box system. Each system is built from 6061, T-6 aluminum alloy to ensure the lightest design possible. Most systems are certified or pending to be CARB Compliant / Exempt.

Key Features:
  • MR Technology: A patented step-down process featured in most applications. It tunes the intakes to factory air/fuel ratios.
  • Air Fusion Technology: A patented method of controlling short term and long term fuel trim levels to factory specs. Featured in some newer applications.
  • Air Horn Technology: A patent-pending design that reduces turbulence and straightens air as it passes through the Mass Air Flow (MAF) sensor. Featured in some newer applications.
  • Injen Super-Nano Dry Air Filters: A dry nano-fiber filtration media so advanced even the U.S. military uses it.
  • All intakes are tuned, calibrated, and then tested on a dyno.
  • Backed by Injen's Limited Lifetime Warranty.
All Injen intake systems now come with a Injen's Super-Nano Fiber Air Filter, which is a dry media and requires no oiling. The new filter media captures/holds more dirt and allows better air flow than conventional air filters. Injen Super-Nano Air Filters also improve engine performance and help engines last longer by keeping them cleaner.
