This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. The air filter is made from Silicone, a premium rubber which will seal better and last longer. It handles as much as 200'c without cracking or tearing. The S&B signature large clear lid provides great looks. A rubber lid seal in included to keep out unwanted engine heat. An integrated box seal keeps out unwanted engine heat. The cooler the air, the greater the dessity, resulting in better performance. The large diameter intake tube feeds more cool air to the throttlebody. More air equals better performance. The Ram Hemi intake features two air inlet points. If you want to customize the amount of air you take in, the kit 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 air flow 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, we recommend that the intake be used without the box plug, except in conditions of extreme heatwave.
