Change Spark Plugs to run ethanol?

[jprescot]

What’s up guys, I got a question about if I should change my stock spark plugs to NGK if I’m running ethanol gas. Is it a must? What do you guys think?

I don’t think the brand of plug matters as much as the heat range of the plug and gap. Check with your tuner and see what they recommend. In the past ive had tuners tell me to run one heat range colder or reduce the gap. But as far as the brands go brand x and brand y they should be the same for the same application. So to answer your question ngk without a specifics part no may not help you and actually be the same as the plugs you have stock
