Drove up to Manchester earlier this week without issue. Came off the M60 about a mile from the office and the car starting misfiring like a good'un

Stuck it in the office car park and, when I'd finished for the day, called the AA.

Turned out the problem was a spark plug had disintegrated and the central electrode had vanished somewhere into the engine.

Thankfully no damage - must have pinged straight out the exhaust port - but could have been nasty.

Anyone had this problem with NGK plugs before?

WOW that sounds lucky!  If it was pinged out the exhaust port it would probably be stuck in the cat, which i think is just as bad.  As i understand it, any foreign object stuck in the cat is bad news.  Can anyone back me up on this??

You may as well use genuine GM plugs, they are quite cheap through trade club.

Cheers

mate of myn had ex police omega. Full service life, but for some reason probably his own, the right bank plug at the back, 6 is it? Dropped the electrode and buggerd the bore, full engine rebuild. Did crank bearings and shells while they where in there, mite as well. It is the most awkward plug to  get at of the 6 but, really there is no excuse. 35 sobs at worst for a set of plugs and a bit of agro with the cable tray to fit them?  
 4 electrode jobs made a big diff. In my old CDX worth a go. As is the lottery mate. Your luck is definatly in. Make the most of it.

I would have hoped 300 motorway miles would have made any problems apparent by now...engine sounds sweet as a nut still...

Sorry was mot implying YOU had no excuse. Was talking about my mate, that plug on his car was not changed because off problems with access. But 6 months old should be ok on reasonable miles. How Queer? Still, sounds like you got away with it. Fancy sharing your lottery numbers this week?

Keep the old plug because there is no way they should fail after 6 months.  if you do suffer any damage try to chace the shop that sold you the plugs then NGK - must have been faulty.  As you say - you think you have no problems fingers crossed

Unfortunately I didn't have my wits about me and the AA man binned it.

Hopefully company car will arrive soon and the miggy will be retired to occasional runaround duty...

Didn't think you were...all I can say is I'm b!##dy lucky and wish I'd bought one...
