Spark plug replacement time....

[Mark_T]

Have you tested that theory (by gapping your plugs, and then re-checking the gap 1,2, or 3 years later)? I think you'd be surprised by how little, if any, they changed.

I can't speak for the Boxster because I haven't checked, but I pull the plugs from my lawn mower and snowblower every year and the gap is always still bang-on .030"

Reference spark plugs.

I have a 1999 Boxster, so my interval between spark plug changes is 30,000 miles.

I personally enjoy changing mine, but I wonder if I can go up to 48,000 miles between changes as recommended for a 2001 3.2L.

Plugs are cheap and each time I replace mine, I see very little wear/degradation.

Just my thoughts

I am still seeing a chiropractor and massage therapist 4 months after changing mine...tight squeeze and a lot of pulled muscle on a couple of those...lol.
