Service director says the plugs cost $212 for four and she’s afraid she won’t get reimbursed by MINI.

I read this to mean that always use these plugs at the standard reccommended intervals instead of the “non” JCW cars.

That is not true. I searched the web and you can find them for $8-9… the NGK site actually lists them for the 2006 Porsche 911 w/3.6L H6 engine.

Given how rich I saw the A/F ratios get when we dyno’d ours (especially at higher rpm), I don’t find replacing the plugs at each interval to be that ridiculous. I mean, the A/F dipped BELOW 10:1 @ 6250 and never came back up. Its conservative fuel tuning to make sure that it doesn’t detonate, but excessively rich A/F ratios can be really hard on spark plugs (this is why they are jet black when you pull them out). Does the stock Cooper S run this rich? This might be the reason why.

Ok then. If you have a JCW MINI and don’t think it’s necessary then don’t bother. I’m just reading the English from the “Official” BMW/MINI install instructions and taking that for fact. Some people think I’m reading it incorrectly but my dealer read it the same way I did and besides what can it hurt?

Do I think it’s extreme? Maybe, but why should I turn down free parts. I’m not trying to confuse people just help them out. It’s not that complicated.

Is it that hard to believe that when you spend six grand for an upgrade that you might also get a couple sets of new plugs in the first three years? And when was the last time someone said, “You changed the plugs too often on that car.”

BTW – Gabe, I know you’re being facetious. : )

I love you guys, but on this one, I think we’ve been led needlessly astray! ;-)

Yeah… stop leading us astray Todd!!!!!!! :-)

i mean, when you think about it, it seems absurd that the plugs need to be changed everytime.

I agree. But hell, I’ll take new plugs if they’re being offered.

Yes, I am questioning the statements made both here as well as on WRR.

The langauge in the “Document” reads very clearly to me but one mans interpretaion is just still an opinion.

Unless the statements made can be substantiated by an individual directly associated with the vehicles

srvice requirements then i fail to see the point of this discussion.

I do not believe a grain of salt of opinion spewed by the local dealer network.

There have been more than a few unrecognized concerns with my vehicle alone.

My question is then is there anyone able to give merit to these statements or should i take this info as fact or some new religion and go blindly spending on faith.
