The Injen Cold Air Intake has been one of the favorites amongst performance enthusiasts for many years. The reason the Injen Cold Air Intake has been so popular is simple - it does what it claims! The Injen Cold Air Intake substantially improves horsepower and torque, and next to most of the listings below, the actual horsepower and torque gain is mentioned. These gains come direct from Injen, and these are from Injen doing countless dyno tests and tuning of the intake to produce the most power! Once Injen believes their Cold Air Intake Kit is the best on the market, they release it.

The Injen Cold Air Intake kit is simple to install, and can be done with hand tools. This cold air intake specifically places the air filter as far away from the engine heat as possible, while using just enough intake piping (not too little and not too much) to perfectly balance the power through the RPM band. Don't be fooled by cheaper cold air intakes that are simply pipes with an air filter, that have no technology or research and development behind them. These genuine Injen Cold Air Intakes are one of our favorites, and a proven winner!

Injen Cold Air Intakes are available in Polished or Black, and in some cases such as Subaru, they are available in wrinkle red or wrinkle black. See the color choices below.
