NEW SNAP-IN LID DESIGN
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. (Patent Pending)
PREMIUM SILICONE COMPONENTS
The air filter, coupler, lid seal and box plug are all made with silicone. Silicone is a premium rubber that will seal better and last longer. It handles temperatures as high as 400F without cracking or tearing and won't deteriorate over time.
CHOOSE YOUR AIRFLOW
More air equals better performance. The Duramax L5P 6.6L intake features three air inlet points. If you want to customize the amount of air you take in, S&B provides an optional box plug that can seal off one inlet point.
When to use the Box Plug?
Stock intake boxes are a significant contributor to poor airflow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With that said, S&B recognizes the benefits of cooler air, so they have included a plug to seal off the opening if desired. For optimal performance, S&B recommends that the intake be used without the box plug, except in conditions of an extreme heatwave.
SILICONE HOOD SCOOP SEAL
The L5P intake kit features a silicone air scoop seal that integrates with the OEM hood scoop and feeds air to the filter. More airflow equals better performance.
S&B tests are performed in their climate-controlled laboratory according to the ISO5011 Test Standard. They also test at the highest-rated CFM for your vehicle when determining the efficiency rate to ensure your engine will be protected. To view these test results, Please Click Here.
