S&B's cold air intake for the 2019 Dodge RAM 5.7L HEMI was engineered to minimize air restriction with a custom enclousure that protects the filter from engine heat and dirt. 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 air filter is made from Silicone, a premium rubber which will seal better and last longer. It handles as much as 400F without cracking or tearing. Demand Better. Demand S&B. Their 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, we provide an optional box plug that can seal off one inlet point. 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 we 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.
