This Stage-2 Sealed cold air intake produces 13 hp, 21 lbs. x ft. torque and outflows the factory intake by 119%. Fully enclosed in a heat-shielding molded plastic housing; this air intake system features a washable/reusable conical air filter that improves airflow for increased horsepower and torque. The housing features auxiliary inlet duct for better airflow as well as an attractive brushed aluminum cover that provides ready access to the filter for servicing. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

Sealed Intake Design — A completely sealed rotomold plastic housing with a clear coat anodized aluminum top keeps warm engine air out and allows for a cooler, fresher, denser air intake charge.

Auxiliary air scoop — The sealed housing features an auxiliary air inlet scoop that allows for increased air volume into the intake for increased performance and improved throttle response.

5-1/2" Conical Air Filter with Inverted Top - This intake utilizes a huge, 5-1/2" conical Pro 5R performance air filter with inverted top for maximum flow. This 5-layer progressive, oiled cotton gauze air filter provides maximum flow for increased horsepower and torque.

Hassle-Free Installation — aFe has developed this intake to provide a hassle-free installation that utilizes all factory mounting locations.

Dyno Tuned Intake Tube — The intake tube has been engineered and dyno tested for maximum air flow and velocity for increased performance. All emissions components and bracket locations are used for a hassle-free installation.

Killer results
I bought this to replace a K&N filter I spent hundreds on (you know the one with the heat shield?) After installing this I immediately had a difference in sound at idle. The Throttle is more responsive and sound amazing! when punching it! Install time 45mins -1hr from stock, but about 30 mins or less if you already have aftermarket setup.
