76mm Throttle Body Kit | VQ37VHR / VQ35HR

1/13

Your factory throttle body on the VQ engine is a restriction. This 76mm throttle body kit replaces it with OEM Hitachi units and precision-machined TriggaSpec spacers for sharper throttle response, stronger midrange, and more top-end power — naturally aspirated or boosted.

Key Benefits

OEM Hitachi 76mm throttle bodies — not cheap aftermarket units
Compatible with stock manifold setups, but pairs best with a ported manifold and intakes for maximum gains
Built with OEM-level fitment and reliability
Works for naturally aspirated or boosted VQ builds — street, track, drift, or drag
