S&B's new snap-in lid design requires no screws to secure it to the box, this makes installation and inspection quick and easy, as the filter can be installed and removed without having to remove the intake tube. Their silicone edge trim ensures an airtight seal, protecting against unwanted power-robbing engine heat. The SB75-5137D intake kit has 3 airflow configurations. Its Unique Airbox design provides more air to the filter by using a scoop that captures cool air from the front quarter panel. This kit comes with a large, highly efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Cleanable media. Both filters feature a black powder coated steel cage for added protection. The kit was designed to avoid check engine lights by maintaining proper airflow mapping of the Mass Air Flow Sensor.
