The latest from Injen Technologies, the Evolution Air Intake System, is the next generation of high performance intakes, offering a factory like appearance with true Injen performance. The Injen Evolution System features a filter box with Injen's latest high-flow designs, as is always true with Injen. The Evolution Intake is properly tuned to your specific engine for maximum power. Always applying the latest technologies, the Evolution Air Intake System is formed with Rotomolded Polyethylene for durability and performance, ensuring you'll get plenty of power for years to come. A powerful and effective intake, the Evolution is sure give you that extra power you're craving.

Key Features:
  • Maximum power with a clean OEM look.
  • Rotomolded Polyethylene construction for maximum durability and heat protection (allows for the cooler air to enter the filter).
  • Injen Super-Nano Dry Air Filters: A dry nano-fiber filtration media so advanced even the U.S. military uses it.
  • Built-in Filter Minder that allows you to keep track of when to service your filter (only available on select applications).
  • All intakes are tuned, calibrated, and then tested on a dyno.
  • Features Injen's new Twist-Lock system to easily and securely attach to the filter.
  • 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.
