Buick Grand National T-Type Idle Air Control Valve Angle Boss.

This Angle boss for the IAC motor mounts the IAC at a 45 deg angle to allow for larger than 3″ MAF pipes. Machined from billet aluminum it takes care of all fitment issues and allows even up to 5″ MAF pipes. Comes with all mounting hardware and gaskets.

As you can see from the picture above this leaves plenty of room for large MAF pipes and hoses. This particular hose is 5″ dia. Notice how there is plenty of clearance to even remove the IAC motor without even removing the MAF pipe. This is a nice piece.

Price; $69
