RFI Intake Ford Powerstroke 6.0L 03-04 & 06-07 $303.59 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 air intake system along 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 6.0L RFI is 100% efficient at cruise intake temperatures match ambient air temperatures.

By replacing the restrictive stock induction, RFI increases horsepower, torque, fuel efficiency, and decreases exhaust gas temperatures. By removing the stock air box, replacing it with a metal heat shield, and using a conical air filter you can maximize the air filter cleaning area and allow the engine to breathe easier and produce more horsepower. All RFI inductions use a lifetime reusable 4” layer cotton gauze filter. This design, combined with deep pleats, make these filters ideal for high performance use. [ More Information ]
