Excellent Performance Spark

I recently swapped my old marine spark plugs for these specialty ones and have been incredibly impressed with their performance. I've noticed a smoother ride, improved fuel efficiency, and no issues with starting up. These spark plugs are also incredibly durable, making them a reliable choice for marine enthusiasts.

Pros
  • Improved performance, durability
Cons
  • No cons to report

Always Recommend Delco AC Spark Plugs

This spark plug is a great choice for any Vortec SBC and is recommended by Chevrolet for many of its engines in boxes like Well. They are one notch cooler than standard Vortec 5.7 truck engines.

Pros
  • Don't just clean your used spark plugs, replace them with new high performance spark plugs
Cons
  • Replacement Availability

Good Spark Plugs - Spark Plugs & Wires

Installed 2 sets on a houseboat (2 Merc Cruise 350 engines). They came already gapped and ready to plug in, I tested them to make sure everything is in the correct gap. Using them on a marine engine is a good idea as the plugs themselves are made of stainless steel so they won't rust from too much water. I had original candles AC 41-93225328284

Pros
  • Install Type: Vehicle Specific
Cons
  • Not as thick as other picks
