BEST PLUG FOR YOUR CAR
NUY THE LESS EPENSIVE SPARK PLG AND EPLACE IT INSTED OF CLEANING. FANCY SPARK PLUGS AE FOR HRD TO REACH HOLES. USE THE RECOMENDED PLUG IRIDIU ONLY FOR AN IRIDUM FROM THE FACTORY DOUBLE PLATNUM ONLY FOR A CAR ORGINLY SOLD WITH DOUBLE PLATNUM. NO OTHER PLUG IS GOING TO IMPROVE THINGS. IT MIGHT BE WORSE BECAUSE IT MIGHT INCREASE THE ENGIN TEMPERATURE THE ENGINERE STARTED WITH, FOR BETTER PERFOMANCE USE V POWER PREMIUM GASOLENS. OCTANE BOOSTER WILL DECREASE PERFORMANCE UNLR=ESS YOU HAVE A HIGH COMPRESION ENGINE. LUCASE OIL UPPER CYLINDER LUBRACANT ADD ONE QUART TO A TANK

ACDelco R42XLS Professional Conventional Spark Plug
Unlike the Champion N9Y sparkplug, the R42XLS does respond to my gasoline powered vehicle with a conventional carburetor.A perfect alternative for the MotorCraft AGR32 and N9Y Champion sparkplug.It (R42XLS)delivers powerful spark and lives up to the phrase "conventional".I do hope it will be available next time my four-cylinder engine needs a sparkplug replacement.
