76mm Throttle Body Kit | IS350 / GS350 | 2GR-FSE

Your factory 2GR-FSE throttle body is a restriction. This 76mm throttle body kit upgrade 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.

What's Included

1x OEM Hitachi throttle bodies
1x precision-machined TriggaSpec spacers
Single wiring harness
All installation hardware
QR code installation video guide

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 2GR-FSE builds — street, track, drift, or drag
