Review on 🔌 ACDelco R42XLS Professional Conventional Spark Plug by Jose Strong

NUY LESS EXPENSIVE PLG SPARK PLUG REPLACEMENT AND REPLACEMENT INSTEAD OF CLEANING. FAILED AE SPARK PLUGS FOR HRD TO REACH THE HOLES. USE RECOMMENDED IRIDIU PLUG ONLY FOR IRIDUM FROM DOUBLE PLATNUM FACTORY ONLY FOR VEHICLES SOLD WITH DOUBLE PLATNUM. NO OTHER PLUG WILL IMPROVE THINGS. IT CAN BE WORSE AS IT CAN RISE THE ENGINE TEMPERATURE WHERE THE ENGINE STARTED. USE V POWER PREMIUM PETROL LENSES FOR IMPROVED PERFORMANCE. OCTANE BOOSTER REDUCES POWER IF YOU DON'T HAVE A HIGH COMPRESSION ENGINE. ADD LUCASE OIL TOP CYLINDER LUBRICANT ONE QUARTER TO TANK
