The Jammer cold air intake includes a pre-oiled filter, and air box, and an oversized intake pipe. The air box helps to keep hot air from the engine, allowing the intake to pull in colder, denser air, and the thermal plastic intake tube further helps to reduce intake air temperatures.

DiabloSport dyno tests all of their application specific tunes to ensure maximum horsepower and torque. The i3 and Jammer intake are designed to work together, which will not only maximize performance gains, but will also avoid check engine lights. So, if you're ready to add some serious power to your truck, the Reaper performance package is waiting.
