LS1 to LS2 Intake Manifold Adapter Natural Finish
CBM's custom intake manifold adapter for LS1 to LS2 throttle body. This adapter allows the use of a LS2 style throttle body to be used with an LS1/LS6 style intake manifold. This adapter will work with any three bolt intake manifold (LS1, LS6, truck style) and four bolt throttle body (LS2, LS3, LS7, L92, L99, L76).
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. CBM spent over a month designing and testing prototypes before we released this one. The port size is 90mm on the throttle body side and tapers to match the 75mm port on the intake manifold. We have designed this piece with an o-ring for a leak free seal and no messy silicone. Have a 92mm FAST throttle body? No problem, this adapter will work perfectly.
