TRE - GM Fuel Injector O-Ring (FIOR-206S)

Replace your worn, cracked, or damaged fuel injector O-rings with new ones made of durable high-temp Viton material. Your vehicle's fuel injectors operate under extreme pressure to deliver fuel to your cylinders, and are fitted with O-Rings to prevent leakage of fuel onto high engine components or to prevent unmetered air from entering the intake manifold. These operating conditions are tough on sealing materials, and o-rings must be capable of sealing as low as -40 C to as high as 150 C and be highly resistant to aggressive and corrosive automotive fuels like E85.
