Our adapter allows you to swap to a Toyota 76mm big bore throttle body which provides a 25% increase in size over OEM. Made from CNC billet aluminum that we anodize for corrosion resistance, provide o-ring gaskets for a leak free seal, and all the necessary hardware to complete the install.

- Must have FMIC piping (piping modification may be necessary).
- You will need a new transition coupler and clamp to fit the big bore TB (3.5") to your piping.
- You will need an aftermarket MAP sensor and relocate it to the intake manifold or a vacuum block.
- You will need to have your tuner adjust your tune for the big bore TB and aftermarket MAP sensor.
