Spark Plug Question

[kaishiz]

How long do spark plugs last for?
How many Kms until they are done?

[mrVT]

every 10.000ks or every 2 years correct me if iam wrong anyone?

go with gm spark plugs ull be suprised how cheap they are and there pretty good or else go with ngk or bosch ones!

Depends on the type of plug. Have you checked the owners manual? It should have the service schedule which will tell you how often to change them.

Mine are long-life ones so they only need changing every 90,000kms, but standard plugs are more like 40-50,000kms

I just replaced my NGK plugs last week and they had done 49,200 K's, never had them out in that time. They were worn a little around the electrode edges, but the gap was only 0.05mm bigger than from new. They had virtually no deposits on them and I was tempted to give them a file and re-gap and put them back for another run, but since they are so cheap I put a new set in. The engine runs with NO noticable differance, starts, idles etc just the same as always.

just curious how are the NGK plugs each to buy?

[pablo]

I would assume that they are around the $4-$4.50 each mark now. I bought mine several years ago when one of those auto shops had a 25% off day and put them on my 'spares shelf'.

Replace them every 40,000kms or two years. Plugs are cheap and easy to replace.
