Plugs - To change or not to change

[Larry C]

In a few months I’m due for my four year service for my 2022 718 GTS 4.0. I only have 13,000 miles on the odometer. The dealership says that my spark plugs need to be changed because it’s four years. My independent shop told me that I can wait until 30,000 miles to change the spark plugs. I’m not sure if I should have the plugs changed. Thoughts? Recommendations?
Thanks!

I just had mine changed in the turbo at 8500 miles, during its 4 year servicing. The tech said the plugs would last much much longer but Porsche wants them changed every 4 years so they won't corrode and seize in the threads. I don't know how likely that is in general, and especially in Los Angeles.... Many car makers set ridiculously long spark plug intervals these days so they can advertise how the car doesn't need a tune-up for the first billion miles, so I kind of doubt Porsche would recommend short intervals unless there was 'something' behind it.

I changed mine in my GTS 4.0 6 months ago. I thought it would be sort of a write of passage to change my plugs, still getting to know the car. I think the OG plugs looked great, no oil, no buildup, not signs of running strange and no corrosion. That being said, they recommend every 4 years and I don't have any compelling evidence to suggest to you one way or another.

Good Luck With your Decision.

My choice is to follow what Porsche recommends just because, well, Porsche.

Ja, Porsche sayzz, sew ve moost du itt! Agree with blue, what the heck, and likely after 4 years also a good thing to check as preventive maintenance.

Good point on the preventative - a chance for techs to take a gander at things in addition to the benefits of the new sparkys.

I will add that Porsche is fairly adamant on changing the plugs and doing all the other service per their maint schedule. Porsche also doesn't care whether it's low miles or not. They want things done at whichever comes first - miles or the time.
Porsche techs and most good independent Porsche mechanics will also generally say the same. Following the schedule is never a wrong choice.

There's also the Karma thing.............................

Change them, that is what I have seen elsewhere.
Would be Too much risk for my tastes not too, it’s the seizing thing.

Thank you all for your responses. The plugs will be changed!

I changed mine at 27k miles, 4 years after in-service date. That was actually 5 years from build. (The car sat unsold at the dealer for almost 10 months after delivery.) Mine came out OK, but they seemed to have early signs of corrosion in the threads. So the 4 year limit seems like a good idea to me.

This.

I had a very scary time removing almost-seized plugs that the PO had not changed on time, despite low mileage. This was on a 2L 718, so not perfectly comparable.
