More Airflow. Better Performance.
Engineered for optimum airflow, this Air intake System is designed to improve airflow up to 51.83% over the stock system by eliminating choke points and restrictive angles found on the factory system. 
Enclosed Air Box
A fully enclosed airbox surrounds the Cold Air Intake and blocks out engine heat and large debris from entering the system. The airbox features S&B’s innovative snap-in lid design that does not require screws and makes installation, inspection, and filter maintenance quick and easy. 
Premium Silicone Parts
S&B constructs this Cold Air Intake with quality Silicone couplers that are durable and create an airtight seal. Silicone is durable yet elastic enough to stretch, then snap into a perfect seal. It is a premium rubber that can withstand temperatures up to 400° F and won't crack or tear with age.
Full Silicone Hood Scoop
This Cold Air Intake includes a Silicone hood scoop seal that integrates with the OEM hood scoop to send the air directly to the system’s air filter for a better airflow.
