Spectre’s MAF sensor mount accepts GM LS3/LS7 or Ford Coyote blade-style mass air flow sensors and is intended for custom intake systems. The raw-aluminum pad fits 3.5" or 4" tubing and is designed to be welded onto the tube for secure installation. It enables use of blade-style MAFs in fabricated intakes where an OEM-style mounting solution is needed.
