How often should you change the plugs?

[@LenartoGarage]

It’s debatable. Many people go 100k without issue. Personally, I’ll change them every 15-20k miles. If you’re tuned, you’ll want to change them more often.

[@samkrboyan]

where can I get the spark plugs ?

[@LenartoGarage]

You’ll just want to search the part number and find the best price. FCP Euro is always a good option (if they have them) due to their lifetime warranty.

Is the car tuned? Why the plug change so early?

[@LenartoGarage]

When the car was cold, I had a minor vibration at idle. I wanted to see if changing the plugs fixed that vibration. They did not fix the vibration, but it still gives me peace of mind knowing I have fresh spark plugs, gapped, and torqued correctly.

@@LenartoGarage ahh yes mine does that as well from what I’ve read it’s a characteristic of the s58.

[@kevinarredondo62]

Spark plug intervals for this motor (s58) is every 20-30k miles

Do you know what the stock gap is?

[@LenartoGarage]

I believe factory is 0.030

@@LenartoGarage Did you get rid of your G82 for the F90?

[@LenartoGarage]

@@zerixzerix3039 Yep. I just sold the F90 now as well. Picked up a 2024 GMC Sierra 1500 Denali Ultimate.
I still have the 986 boxster as my fun car. I may pick up a 997 4s after I’m done fixing up the boxster. I’m leaning towards smaller and older sports cars to get more excitement/feel out of them.
