Bully Dog Filters & Intakes


RFI Cold Air Intake, Enclosed System

This fully enclosed air intake system is designed to keep hot air out of the intake air stream. This intake seals tightly against cold air sources from within the engine bay, which ensures an improvement in performance and efficiency. Through real world and user testing Bully Dog has proven that an enclosed intake system alone with a high flow cotton gauze filter will yield better air flow and colder intake temperatures than a stock system and an aftermarket open intake design. Our result proves that this is a superior intake system.

Proven Results:
· 10% Greater Air Flow at 60 mph in cruise control
· 10 degree lower intake temps at 60 mph in cruise control
· 10-15 added horsepower on a Mustang chassis dynamometer
· 10-30 added Ft.-Lbs. of Torque on a Mustang dynamometer
