Holley EFI 12-1 Crank Trigger Kits - The Best Way To Get Accurate Spark Timing

Spark timing is the key to making your engine produce maximum power. And the best way to get accurate spark timing is with a Holley EFI 12-1 Crank Trigger Kit. A crank trigger kit bolts directly to the crankshaft, so the timing is determined by the position of the crankshaft itself. Meaning there are no mechanical variables to worry about. Your timing is going to be accurate, no matter what. Holley EFI's 12-1 crank trigger wheel has twice as many teeth as a standard 4-1 wheel. And that means that the crankshaft position sensor can more accurately determine the position of the crankshaft.
