2200cc Pontiac G8 / GXP LS3 Fuel Injectors – NEW Extreme‑Performance 2008–2010 | SouthBay

Push the limits of your Pontiac G8 / GXP LS3 (2008–2010) with SouthBay’s brand‑new 2200cc extreme‑performance fuel injectors. Engineered for maximum fueling capacity, these injectors support high‑boost turbo systems, supercharged builds, stroker engines, aggressive cam packages, and full E85 conversions.

These are 100% NEW injectors — never rebuilt — built with stainless‑steel internals for long‑term durability under extreme temperature and pressure. Every set is dynamically flow‑matched to ensure consistent AFR, smooth idle, and reliable performance during aggressive tuning.

Perfect for drag builds, high‑horsepower street cars, and fully‑built LS3 engines demanding massive, accurate fuel delivery.

Performance Features:

• True 2200cc/min flow rate for extreme‑output LS3 applications

• Brand‑new injectors (NOT remanufactured)

• High‑impedance design compatible with factory & standalone ECUs

• Stainless‑steel internal components for maximum durability

• Compatible with pump gas

• ⚠️ Important: E85 Usage & Maintenance Warning The internal components of the 2200cc Bosch core are highly sensitive to the "gumming" or sticking effect that can occur with ethanol-based fuels.

  • Storage Recommendation: If the vehicle will be stored for more than 2 weeks, we strictly recommend flushing the fuel system with standard 91/93 octane gasoline.
