Looking for more resolution for your crank pickup? This 36 (minus 2) tooth wheel is your answer. More resolution means more accurate timing information, especially when your engine speed is changing rapidly. Designed to use factory sensors, this bolts in place of the OE four tooth wheel on 1996-05 cars and can be retrofitted to all "long nose" engines from 1991 to 2005. Not compatible with stock engine computers, this is for Miatas with a Hydra 2.7 or some other form of replacement ECU that can handle a 36-2 wheel.
Suitable only for stock harmonic balancer pulley.
