This spacer fits the Magnuson Gen2 or LSA/LT4/5 style 2650 blowers (as opposed to the jackshaft style). This spacer uses a gasket on both sides of the blower outlet area to make sure there are no boost leaks through the spacer, as well as a gasket on the bottom side of the spacer to the blower case. Longer mounting hardware and gaskets are included. Additional ports for MAP sensors, Hobbs switches, or NOS/Meth nozzles can be added as needed, contact us for details. The minimum thickness to add ports to the spacer is 3/4" in both billet and phenolic.
