Spark Plug lifespan

[ARC]

Hello guys.
56k on my 2022 and wondering when I need to change the plugs.
Been running a tune on it since 15k.
Seems to run fine just looking to do preventive maintenance.
Thanks,

Do it. Spark plugs may be fine but gap widens. It's kind of a pain so just put in new plugs.

Ok, but after looking at the space I'm paying someone to do it!
At 48 I'm done with the young guy work.

It takes about an hour…not hard at all. A little tedious but not hard. As for lifespan…30-30k if tuned. They eat plugs like candy. Go a gear range colder gapped at .028. The NGK Ruthenium’s are the smoothest I’ve ran so far.

I was going to just go with the OEM motorcraft again. I run E50 daily. I havent had any problems with the motorcraft plugs, and im at 55k now. Original set and tuned for the past 40k. Maybe ask the tuner if the gap should be smaller than the stock.
