The undisputed leader in fuel systems for over 100 years, including Holley crankshaft trigger sensors and pigtails. Their Performance products have powered every NASCAR Sprint Cup team and nearly every NHRA Pro-Stock champion for four decades. They're clearly experts in the field of engine parts,
These sensors are fitted to detect the degree of crank rotation, so the engine can inject fuel and spark the coils at just the right time.
