Nissan Q45 80mm Throttle body flange

This large bore billet flange is machined to fit the Infinity Q45 80mm throttle body with the back side opening of 3.22" (82mm). We've tapped for the 8mm bolts on the square Q45 pattern. The Q45 is commonly called a 90mm, this is actually the outside diameter where the intake pipe coupling will go, not the actual 80mm butterfly diameter.

Made from 6061 T6 billet aluminum, this flange can easily be welded onto an existing manifold or used for a complete custom manifold.

This is for the machined flange only. Throttle body not included.
