 HEETSHEETTM Applications


HeetSheet fits 1968 1/2 to '89 911 engines using factory exhaust systems and aftermarket replacement heat exchangers. These engines have a lower valve cover with 11 attachment nuts. Order Model No. HS-1.

HeetSheets will fit on '75-77 911's equipped with factory thermal reactors with slight modifications. Contact us for details.

HeetSheets will fit on '76-89 Turbos.

Due to space restrictions, you should verify fit on engines using aftermarket racing exhaust headers. See "Rule of Thumb Fitment" below.

HeetSheet has been tested and is compatible with heat exchangers manufactured by SSI.

HeetSheets may not fit all 914-6s. Due to the tight clearance between the engine and chassis, the engine must be exactly centered. This installation seems to be most successful on modified 914s with a 911 engine conversion.

HeetSheets for Porsche 993. Coming soon. Contact us and we'll let you know when this happens.

All 911 engine applications:
HeetSheet requires approximately 1.25" (32mm) of clear space in front of the lower valve cover. HeetSheets will fit if this minimum space is available.
