Klotz Cleanest Fuel System Cleaner for 2 & 4-Stroke Engines - Enhanced Fuel Injector Performance & Carbon Neutralizer - KL-620 (2 Bottles)

Klotz Fuel System Cleaner is designed for automotive, powersports, and power tool equipment. It uses a combination of technologies to target carbon deposits in two-stroke and four-stroke gasoline engine configurations. These powerful additives will clean upstream hardware (intake valves), downstream hardware (post-catalyst oxygen sensor), and everything in between. The formulation also contains surfactant chemistry that will continue to clean the fuel system after the treated gasoline is exhausted. Designed for automotive, powersports, and power tool equipment using carburetion, gasoline direct injection (GDI), turbocharged gasoline direct injection (TGDI), or port fuel injection (PFI) systems. For use in two- and four-stroke engines. Not recommended for alcohol-based fuels with blends of E70 or higher.
