The Racer X Fabrication coolant neck for the 1991-1995 Toyota MR2 is a direct replacement for the OEM coolant neck. This unique design allows for complete customization of the coolant neck. It has (2) 1/8 NPT ports on either side of the outlet which can be used with an aftermarket temperature gauge and a coolant port for a water cooled turbo.


The Racer X coolant neck is CNC machined from 6061-T6 aluminum and uses a common 12AN thread size for the pressure cap and 16AN for the coolant outlet. The pressure cap location retains the OEM placement so coolant flow is uninterrupted and allows the coolant system to function as intended.
