Use this adapter to bolt your RX8 throttle body to an S2000 or k20/k24 intake manifold when swapping a K series into your RX8 for a cheap 70mm big bore throttle body. Also has an added benefit of adding 0.1 liters to your intake plenum volume.
You’ll need an 06-09 Honda S2000 drive by wire intake manifold and an 04-11 Mazda RX8 throttle body.
This kit comes with all necessary hardware. You’ll need an OEM k24 throttle body gasket and RTV(not supplied).
