WHAT THE HECK DOES INDEXING A SPARK PLUG MEAN? CAN YOU INCREASE POWER BY INDEXING SPARK PLUGS? SHOULD YOU EVEN WORRY ABOUT IT? HOW HARD IS IT TO INDEX SPARK PLUGS? WILL IT ADD MPG? CHECK OUT THIS VIDEO WHERE I STARTED WITH A BTR-CAMMED 5.3L L33 EQUIPPED WITH A FAST INTAKE, THEN INDEXED THE PLUGS SO THEY ALL AIMED AT THE SAME SPOT ON THE COMBUSTION CHAMBER. I THEN AIMED THE OPENING OF THE ELECTRODES OF ALL PLUGS AT THE INTAKE VALVE. I THEN DID THE SAME WITH ALL THE ELECTRODES AIMED AT THE EXHAUST VALVES! WAS THERE ANY POWER GAIN FROM ALL THIS WORK? CHECK IT OUT!
