I'm gonna be getting my '06 GT roadster remapped soon but wanna do a few health check things first, like oil & filter, fuel filter, aux belts & the spark plugs. Now I've heard about "spark plug upgrades" when chucking more power through like going 1 grade colder, also known as just getting a slightly smaller gapped plug. Has anyone actually done this? Will it really make any difference on a N/A car that only looking to go stage 1 remap? Gotta be iridium anyhoo so is there a brand that seems to work better than another on the DE engine? I may have this thread in the wrong section as its been a long while since I last posted. Any help on this matter will be muchly appreciated.ðŸ˜
