microflex®974 Injector Direct Protection

microflex® 974 prevents fuel-related deposits in injectors thanks to innovative ROA² technology that forms a molecular-active protective film. It thereby minimises fuel consumption and keeps emissions values low. When added to the fuel tank, the fuel is proven to remain within the DIN EN 228 fuel standard.
