One step colder plugs for N/A

[Scooters]

I recently installed a Boss intake and when I went to get retuned the ECU was pulling timing. My tuner pulled a plug and it was shot. He suggested going to a one step colder spark plug with the replacements.

Ford Racing 5.0L Mustang 4V Heat Range 0 Spark Plugs (11-14 5.0L) M-12405-M50 - Free Shipping!

The description says for supercharged or nitrous applications. Has anyone used these on their N/A coyote.

Thanks,

Scott

Never heard the need for 1 step colder plugs on n/a application.

i dont see a need to put colder plugs on an n/a aplication especially with stock compression. your tuner might be a bit off.

You dont need a colder plug. I used the stock heat range with a 150 shot for a whole season.

When you ran the stock plugs on the 150 shot did you regap them? I will be running the plugs that the OP listed in this thread for my nitrous application.
