Proflow's drive-by-wire (Fly-By-Wire) throttle bodies are a perfect upgrade for any late model LS/LSX engine and your Commodore Direct replacement. They are precision machined from 6061 billet aluminium and come in multiple finishes. The unique blade design allows these throttle bodies to bolt right up to any factory or aftermarket LS/LSX intake manifold and they utilize the original late model GM 6-pin connector. The larger bore 102 or 108mm size allows for increased air flow which results in fast smooth acceleration across all RPM ranges. The proprietary electronics and stepper motor allow these throttle bodies to be used on both naturally aspirated and forced induction engines. Tuning is required for installation.
