Inline Four has developed a special high temperature insulating gasket which replaces the factory throttle body gasket. Introducing iL4 Performance Thermaltech Throttle Body Gaskets. These thermal throttle body gaskets reduce inlet temperatures, act as spacers increasing intake manifold volume, and provide leak free operation for oversized throttle bodies or setups that use wet shots of nitrous or water/meth in the intake piping.
Thermaltech gaskets do not leak, have superb fitment, produce results and are used by racers and enthusiasts around the globe.
Available in 60mm, 65mm, 68mm, 72mm & 70mm for B/D/H/F series engines.
K series applications also available.
