Premium performance plugs with a unique electrode shape featuring Diamond Fire technology that maximizes the spark plugs power
Electrode combines three types of performance and new technology for improved flame kernel shape
Flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during power stroke for more complete combustion and an improvement in engine performance
If your a fine tuner, you will notice a cleaner burn, I've been building and tuning engines for 4 decades now, If an E 3 plug is available for application, I install it. And, recommend these plugs to anyone thats thinking about the crossover from conventional spark plugs to any other type of SPARK PLUG. PERIOD !!!!!!!!
