Spark plug upgrade

[Horizon5.0]

I have a 2019 GT with just over 50k miles on it and the spark plugs have never been changed. In a few days i’m having long tube headers put on and tuned for e85 and i plan on racing my car at a strip every once in a while. since my car will no longer be stock, what spark plugs are best recommended for harder use, longevity, and 460-480whp na applications?

Just stick with the stock plugs. No reason to change.

like get new spark plugs that are oem or don’t bother changing at all?

Agree with robvas. Just get OEM replacements.

I mean at 58k they should be fine

I'd just get a set of NGK iridiums in the stock heat range if you want new ones

Just throw a new set of OEM plugs and youll be good to go.
