As always (and specified below) every spark plug from Race-1 is inspected, pre-gapped for your ignition system with the threads properly lubricated! That's why we call them "READY-TO-RUN!"
RACE-1 READY TO RUN SPARK PLUGS
Race-1 has used the same NGK spark plug in both 602 and 604 engines for nine years.
Race-1 offers the NGKR5724-8 spark plugs to you ready to install.
We pre-gap the plugs for your ignition system and even lube the threads with a special lubricant designed for electrical contact.
