Spark plugs and their lifespan

[v-g]

I just heard from the dealer that the spark plugs don't need replacing before 120.000 km / 75.000 miles / 4 years. I think that's a very long time for something that active in an engine to live.

Are they really right? They ought to be, but...

I'm pretty sure its 40k miles and thats for the standard platinum plugs. Probably worth changing more often if you're re-mapped

Can anyone comment on how these plugs looks? Don't mind the oil spill.

Interesting, my car is 5 years old done 45k and I've been wondering about the sparks, will keep an eye on this.

I just ran out a set of Audi OE (Bosch) plugs in 9,000 miles. Couldn't believe it as I expected 25k from them. Replaced them with NGK Iridiums and they have worked fine. Personally I've always found NGK to be the best of the plug manufacturers.
