92MM tapered down to 75MM

Works with Both gold blade and silver blade 4 bolt throttle bodies. Comes with all hardware required to run either throttle body

Other adapters on the market are too thin and require extra grinding to clear most 4 bolt throttle bodies. Ours are made from a thicker aluminum and no extra grinding is required to use a gold blade or silver blade throttle body.

Comes with a factory style Felpro O ring seal for the 4 bolt side.

Made in the USA from USA aluminum
