Unlike fuel additives that get diluted into fuel before reaching the components of the fuel system, GDIIVDTM Intake Valve Cleaner is sprayed directly into the air intake system and hits the back of the intake valves with PEA (Polyether Amine) detergency at 150X the concentration of any premium fuel additive. No more engine tear-down required for clean intake valves, especially on GDI engines.
Deposits form in every fuel system, but the amount and how quickly they form depends on the quality of fuel and oil you use, your driving style and engine type. GDI (gasoline direct injection) engine intake valves are prone to rapid deposit buildup because they never get cooled or washed with fuel. Deposits form in as few as 5,000 to 10,000 miles, restricting proper airflow and increasing operating temps.
