Restore Factory Power: Red Line SI-1® Complete Fuel System Cleaner

Combat performance loss, rough idling, and reduced fuel economy caused by carbon buildup with Red Line SI-1® Complete Fuel System Cleaner (Part #60103), available now at Straight Six Imports. This is the most powerful concentrated fuel system detergent available, designed to clean your entire fuel system with a single treatment.

SI-1 utilizes the maximum allowed concentration of PEA (Polyether Amine) to aggressively remove hard, stubborn carbon deposits from critical areas: fuel injectors, intake valves (in PFI systems), and combustion chambers. This maintenance is essential for all modern Gasoline Direct Injection (GDI) engines and high-output turbocharged platforms.

Key Features for Performance and Efficiency:

• Max Concentration PEA: Cleans dirty injectors to nearly 100% efficiency in one treatment, restoring optimal fuel spray patterns and maximizing horsepower.

• Octane Requirement Reduction: By cleaning combustion chamber deposits, SI-1 can reduce your engine's octane requirement by up to two numbers, helping to eliminate engine knock and pinging.

• GDI & Turbo Engine Safe: Crucial for GDI engines, keeping injector tips clean and reducing the risk of harmful deposits that cause issues like LSPI (Low Speed Pre-Ignition).

• Upper Cylinder Lubrication: Contains a synthetic upper-cylinder lubricant that helps reduce wear and keeps pollution control valves clean.

• Fuel Economy Improvement: Customers often report fuel economy improvements of up to 12% after initial use, depending on the prior condition of the injectors.

Keep your sophisticated JDM and European engines running flawlessly. Treat your fuel system with Red Line SI-1® (60103) every 3,000 to 5,000 miles for maximum efficiency and power.
