This adapter allows the use of a 90mm, 92mm, 102mm or 105mm style throttle body on a 4150 4 bolt style intake manifold. This adapter is proudly made here in the USA from a solid piece of 6061-T6 aircraft grade aluminum. It is 3/4" thick and milled on every side to ensure a perfect seal.
We spent over a month designing and testing prototypes before we released this one. The bore size is 102mm on the throttle body side and tapers to 92mm on the intake manifold side. This allows the perfect transition of air for a smooth flow and perfect fit.
O-ring and hardware are included. |
