Product Description

Bully Dog Ford 6.4L RFI Intake 51103

Application: 08-11 Ford 6.4L Powerstroke

The enclosed system has a few specific goals in mind:

  • Keeping hot air out of the intake stream. Modern engines are much more specifically engineered than the coal burners of yesterday. Bully Dog’s Rapid Flow Air Intakes have been precision designed and tested for optimal cold air flow and decreased air turbulence.
  • Designed to pull air from cold air sources from within the engine bay. Increased cold air is then fed to the engine, which in turn increases power.
  • Accommodating a high flow cotton gauze air filter. Bully Dog also offers these top of the line air filters.
  • Improving the look of the engine bay with slick-looking style. Our intakes are designed to give your engine bay a nice, sleek, custom finish.
  • Clean Install – Quick and easy install achieved by snap on parts and easily assembled fittings makes the installation process simple.Bully Dog Air FiltersA higher quality air filter is critical to achieving optimal results from an air intake kit. All Bully Dog’s Rapid Flow CAI systems come with the industry’s highest quality filter. Thus, performance is guaranteed.Our Air Filters are manufactured under ISO 5011 specifications to ensure quality. We design our air filters with more surface area than any stock application.
