718 Spark Plug advice - rmbracalente - 10-21-2021
So the plugs in the 718 are rated for ~30K miles. However, Porsche tacitly recommends replacing them every 4 years, allegedly to avoid the plugs becoming seized (I assume because the plug threads are steel & the engine block is aluminum). Was wondering what the common opinion on this was (not necessarily specific to the 718). It’s a 2+ hour/$450-ish job that I’d prefer to avoid until necessary, which from a mileage perspective along could be another 3-4 years.

Most services are time or mileage dependent so whichever comes first. As long as you have a 14mm 12pt swiveling socket it's a 30 minute job. I can give you some more info if interested..
