AFTERMARKET ASSASSINS LOWER HEAT SPARK PLUGS 2016+ RZR XP TURBO
For 2016 models we step down 1 heat range in the spark plug which helps prevent unwanted detonation under higher boost pressures.
2017's come with lower heat plugs from the factory, but they protrude into the cylinder further to compensate for the thicker head gasket. AA found that going with the shorter plug on 2017 models also helps prevent detonation and/or pre ignition.
Great add on for anyone running our tunes on their XPT.
