Review on Enhance Performance with B. Ignition Sensor Kit for MerCruiser Thunderbolt I IV Distributor by Jared Peck

Revainrating 5 out of 5

Mercruiser 4.3L Thunderbolt HEI

Worked great but didn't quite match the wiring. Has an extra ground wire. Just run to the bottom along with the bottom under the distributor cap. Also, don't forget to remove the ground bolt on the distributor, otherwise you may break the bolt holding the sensor on the left side.

Pros
  • Ignition parts
Cons
  • Modernity
