Product Details

The Engineered Marine Products 300-00879 is a high-energy ignition (HEI) coil designed for MerCruiser and Crusader marine engines with Thunderbolt IV and V ignition systems.

Key Features:

  • Converts 12-volt battery power to thousands of volts needed for optimal ignition
  • Designed to handle greater current loads for more complete combustion
  • Includes mounting bracket and hardware for easy installation
  • Built to withstand racing conditions and normal wear and tear

smooth transaction. good seller.

Autoplicity is a great merchant to do business with. They stock a wide variety of high performance parts at rock-bottom prices, and they ship quickly without any hassles. They are a pleasure to deal with.

This was my first purchase on Autoplicity, it has been great will definitely put it in my favorites.

Saved 50% from what the local parts stores were selling it for, even after shipping. Same exact product. I'll definitely be shopping here again. Thanks!

thanks

Excellent prices. Delivery was fast. Great site to order parts from.
