Good To Know

Q: What does this adapter actually do? A: It lets a 4 bolt throttle body bolt to a 3 bolt intake manifold, solving a common bolt pattern mismatch on LS swaps. The sealing ring is included to help the joint hold vacuum.

Q: Will it fit my intake? A: It is intended for LS style 3 bolt intakes paired with a 4 bolt throttle body, so measure both flanges before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
