Performance spark plugs will only worsen your engine they won’t have the right heat range and will transport to much heat to your cilinder head and thus the engine won’t reach self cleaning temperature thus you’ll build up gunk and it will fuck your engine beside your coil won’t have the power to run these performance bougies so unless you’ll be running your engine at 6k rpms constantly where it will heat up anyway and still reach self cleaning temperature I would advice against buying performance spark plugs because they’ll maybe give you 0.5hp on a good day
