NEW SNAP IN LID DESIGN
Our new snap-In lid design requires no screws to secure it to the box. This makes installation and inspection quick and easy. Our silicone edge trim provides a protective seal against unwanted, power-robbing engine heat and debris. This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Extendable media.
The 392 Intake features an integrated hood scoop that provides a tight seal to Jeep's new Hydro Guide hood. When driving through deep water or harsh conditions, water and air will continue to get separated by the Hydro Guide hood technology.
PREMIUM SILICONE COMPONENTS
The air filter, coupler, lid seal and box plug are all made with silicone. Silicone is a premium rubber which will seal better and last longer. It handles temperatures as high as 400F without cracking or tearing and won't deteriorate over time.
NO CHECK ENGINE LIGHTS
S&B devotes a huge amount of resources to engineer our intakes that allow your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights with it's properly mapped Mass Air Flow Sensor.
The OEM intake tube is highly restrictive and flattens out toward the center of the tube. S&B's intake tube doesn't flatten out, and is designed to minimize restriction with one clean line from the throttle body to the air box. Less obstruction means more airflow, and better performance.THE SOUND OF PERFORMANCE! Check out the sound of the intake when installed in the Jeep 392!. A huge air filter and air box results in a more aggressive sound compared to stock
