The Racer X Fabrication valve cover insert for the 91-95 Toyota MR2 is the aesthetic addition your valve cover is missing once you have removed your throttle body support. Many enthusiasts have removed their support stay for machined throttle body inlets and then are left with the unsightly hole in the Gen 2 and Gen 3 valve cover. The Racer X insert now completes your valve cover with a CNC machined aluminum component that matches the valve cover shape and is held in place with stainless steel hardware.
