2.9L and 3.1L EFI Kit

The 2.9/3.1 EFI kit is an extension of the 4 TBI kit sold above with special emphasis of fuel and air flow.  Throttle bodies are bored to 1.25″ for higher flows required foir these special built engines.  You will need a Wide band O2 (WBO2) sensor and a laptop for programming your fuel flow/Air fuel ratio (AFR) for your desired needs.  A narrow band O2 sensor is included in the kit to use after engine has been “dialed in” with the WBO2,
