WEPP 2036+ GDI Protection is specifically designed to clean and protect the injector nozzles of GDI (Gasoline Direct Injection) systems, removing deposits that contribute to increased fuel consumption, reduced performance, poor throttle response, and poor cold-start behavior. It improves friction between the piston and cylinder, enhances exhaust emissions, and removes combustion chamber deposits. It also reduces engine knock and protects the entire injection system against corrosion. WEPP 2036+ GDI Protection is suitable for use in both GDI and port fuel injection engines. One bottle is sufficient for up to 60 liters of fuel.
