Efficient Ignition Upgrade

Thanks to my knowledge gained in practice I can appreciate the efficient operation of this ignition coil. My boat runs smoother and starts up faster .The installation was easy too. The only downside is the price, but the quality makes it worth it..

Pros

Cons
  • Pricey
