Anyone have info on spark plug life....I can't seem to find anywhere in the Manual what the time element is for replacing them - service dept tells me 30k miles

modded they are recommending 10k interval

I just had mine replaced at 3 year mark...or near 40k km.

Was running smoothly before and after...with stage 2 for past 2 years...so almost 24k km.

Going forward, I will replace about every 15k with M-engineering gaped plugs.

Yea with mods, I will do mine every 2nd summer, good to have fresh plugs if you're pushing the boost and using different fuels.

Also, upstream, closed loop O2 sensors are a good thing to change out once and a while to make sure readings are perfect.

Cheers
