Installation and Usage

Installation requires removing the original manifold and transferring the fuel rail, injectors, sensors and vacuum fittings, with new gaskets used throughout. A 75 mm throttle body, or a suitable adapter, will be needed. As the change will affect air flow, the engine should be tuned after fitting, so we recommend installation by a Honda performance specialist.
