Performance Series Spark Plugs - A/C .460" reach, 5/8" hex, tapered

620-MR43T

Performance Series Spark Plugs - A/C .460" reach, 5/8" hex, tapered

These are the most commonly used performance plugs today! These are a stock replacement for Mercruiser BBC and SBC motors.

Ribbed Suppressor Seal, which extends resistance and prevents spark 'flash over' and misfire. Nickel-chrome alloy sheathing to help prevent corrosion on center electrode.

  • Heat Range: 3
  • Resistor Plug: Yes
  • Gap (In): 0.040 Inch
  • Thread Reach (In): 0.430 Inch

Note: Colder plugs work best in supercharged applications and warmer plugs in general performance uses. Most cast iron cylinder heads use tapered spark plug while most aluminum heads use a gasket style plug.
