40K Major Maintenance Question

[epaulbb]

Hey Everyone,

So I'm getting ready to take my 2005 C2 in for the Major Maintenance. I got the official Porsche 05-07 checklist and the 08 updated checklist.

In the 05-07 checklist, it says I need replace spark plugs at 60k and in the 08 checklist is says to replace at 36k.

I've talked to two local Porsche dealers and one says I shoud replace at 36 the other at 60K, the dealer that recommends 36k and says Porsche changed the spec due to the poor gas quality these days.

What do you guys think?

Thanks in advance!

I'd change 'em. In the scope of things, plugs are cheap, and play a huge role. Ask for the old plugs back, so you can inspct them.
