The 87mm GT350 Throttle Body is a great to your intake, but needs an adapter because its bolt pattern is unique. This kit features a smooth transition from the 87mm TB to the 84mm intake opening, which can be easily ported. It also has E85 friendly Viton O-ring seal, so there’s no sealant or shifting paper gaskets to deal with, you just bolt it up and go. Also included is the relocation plate, which is not required for Boss Intake Manifolds, for the purge valve to clear the GT350 throttle body.

Please Note: Once this is installed alongside the required GT350 Throttle Body (not Included), your vehicle will need a custom tune (also not Included).
