Gasoline Direct Injection (GDI) systems have unique carbon build-up issues on intake valves and ports. Detergent additives that are poured into a gas tank do not reach these carbon deposits. Gumout® Regane® Direct Injection Intake Valve & Port Cleaner, which contains Polyetheramine (P.E.A.) – the most advanced cleaning chemistry available, is introduced through the intake system and can reach these deposits. This professional strength formula ensures valves and ports in GDI/direct Injection and standard injection systems are cleaned. The result: better performance and restored gas mileage.

  • Quickly restores lost performance
