Bully Dog RFI Intake Kits

The GM LLM RFI™ system is an enclosed systems that was designed with a few simple goals in mind: keep hot air out of the air intake stream, make sure systems seal tightly up to cold air sources from within the engine bay, accommodate a high flow cotton gauze air filter, and improve the look of the engine bay with a great looking intake. By following these simple goals we are able to provide colder air and more air to the engine. Thus providing better performance than a stock intake; the resulting benefits are improved fuel economy, more horsepower and torque, lower cost of ownership than some stock air intakes, and an upgraded look to engine bay. This system adds 10+hp and 20+ lbs.ft of torque to your Duramax.
