Product Description
Michigan Motorsports LS Injector O-Ring Adapter Set for LS2, LS3 & LS7 Intake Manifolds
Adapts LS1-Style Injectors to LS2, LS3 & LS7 Intake Manifolds | Set of 8
The Michigan Motorsports LS Injector O-Ring Adapter Set is specifically designed to allow standard LS1-style fuel injectors to properly seal in GM LS2, LS3, and LS7 intake manifolds. These later intake manifolds use a larger injector bore diameter, which causes vacuum and intake leaks when standard injector O-rings are used. These custom-molded O-rings correct that mismatch by providing the proper outer diameter seal at the intake manifold side of the injector. They are only required on the lower injector O-ring (intake manifold side) and are molded from Viton-style material to match OEM durability and chemical resistance.
Key Features & Benefits
- Prevents Injector-Related Intake Leaks: Corrects the injector bore size mismatch between LS1 injectors and LS2/LS3/LS7 intake manifolds, eliminating vacuum leaks and unmetered air issues.
- Allows Use of Standard LS1-Style Injectors: Enables reuse of common LS1 injectors when upgrading to LS2, LS3, or LS7 intake manifolds without switching to larger-OD injectors.
- Lower Injector Seal Only: Designed specifically for the intake manifold side of the injector; factory upper O-rings are retained since LS2 and LS7 fuel rails share LS1-size injector bores.
- OEM-Grade Viton Construction: Molded from Viton-style material to provide excellent fuel resistance, temperature stability, and long-term sealing reliability.
- Complete Set for One Engine: Sold as a matched set of eight (8) O-rings to service all injectors on a V8 engine.
