BG GDI Air Intake & Valve Cleaner PN 260BG Air Intake & Valve Cleaner is a BG lab-tested and proof-positive intake cleaner for all engines (both port fuel injection and gasoline direct injection).Sticky, heavy deposits build rapidly on the backs of valves and in air intake systems. Cleaning intake valves requires a potent formula applied with proper equipment, due to both the placement of the injector inside the combustion chamber and the complexity of the intake design.BG Air Intake & Valve Cleaner withstands intake temperatures and pressures and remains in the intake, where many intake cleaners quickly burn off.Following this service, over miles of driving, incoming air will continue to carry liquid-form deposits to be burned harmlessly in the combustion chamber.As part of the BG GDI Fuel/Air Induction Service, BG Air Intake & Valve Cleaner:Restores MPGRestores engine performanceRestores powerReduces harmful emissionsIncludes a Smilyeez pocket screwdriver.
