NGK Laser Iridium Max+ Performance Spark Plug for Mercury Verado L6 300-400 (Set of 6)

Spark plugs are responsible for providing an ignition source inside your engine’s combustion chamber. Energy is transferred from the ignition coil to the plug which creates a spark igniting the air-fuel mixture. The NGK Laser Iridium Max+ Performance Spark Plug spark plugs operate at one heat range colder than stock, which results in better pre-detonation resistance and spark plug life under extreme conditions. This is vital to remove heat from the cylinder head in the Mercury Verado engines. USP recommends upgrading the engine’s spark plugs to NGK Laser Iridium Max+ Performance Spark Plug.

All spark plugs come pre-gapped with a 0.8 mm (0.0315 in.) gap. If the engine is used for any form of racing or extended wide-open-throttle sprints, USP highly recommends upgrading the spark plugs for engine longevity and safety. In the case of engines with added boost pressure over stock, these spark plugs are required. A change interval of 300 hours is required for engine longevity and safety.

Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.
