SI-1 Complete Fuel System Cleaner – 15 oz Fuel Additive for Gasoline Engines – Cleans Fuel Injectors, Combustion Chambers, Valves, and Intake Systems (2 Pack)

The SI-1 Complete Fuel System Cleaner is an advanced fuel treatment solution that improves engine performance and fuel system health by removing carbon deposits, fuel varnish, and gum buildup from fuel injectors, combustion chambers, fuel lines, valves, and intake systems. This powerful fuel additive helps restore lost horsepower, enhances throttle response, and boosts engine efficiency. Formulated with polyetheramine (PEA), the most effective detergent available for modern engines, this fuel cleaner ensures deep cleaning and restores the fuel system to optimal performance. It works with direct injection (GDI) engines, turbocharged engines, and hybrid vehicles to reduce carbon buildup and improve fuel economy, performance, and acceleration. Compatible with all gasoline-powered vehicles, this cleaner is safe for oxygen sensors, catalytic converters, fuel pumps, and spark plugs, ensuring that no damage occurs to your vehicle emissions system. It's the perfect solution for routine maintenance or for restoring engine performance to high-performance vehicles.
