A Cold Air Intake System is often one of the first engine mods that Polaris Slingshot owners do. It not only improves throttle response, but also increases both Horsepower and Torque and in some cases MPG. Installation is simple for all of the cold air intakes we offer and all of the models either come with or offer a heat shield to block unwanted engine heat from entering the backside of the air filter. Injen, DDMWorks and 1320 performance are all proven vendors in the Slingshot market as you can see by the positive reviews of their product. You can't go wrong with any of these great brands.
