Well built sturdy powder coated beauty. Definitely feel a power increase, now after hearing it I'm fighting it now to stomp on the petal.

About Toyota 4Runner Injen Cold Air Intakes

Restrictions in the airflow from your standard air box inhibit your engine’s ability to produce power. A new cold air intake helps to streamline the path air takes to your intake manifold. Increasing the volume of air improves the throttle response and power output. These more efficient parts integrate with your existing engine management system. Installation is simple and requires the use of basic hand tools. Not only do our cold air intake systems look great under the hood, but they also add a subtle intake tone to the sound of your running motor. Order your Toyota 4Runner Injen CAI from AutoAnything today, and take advantage of our 1-Year, Lower Price Guarantee and Free Shipping on every purchase.
