Sorry to hear that Nathan!
And ditch those multi-prong sparkplugs!
A paste of well documented common knowledge:
Q8. Why do some spark plugs have multiple ground electrodes?
A8. This is an attempt by the manufacturers to increase the service life of the spark plug. The ground electrodes can wear down rapidly in some engines. Tiny particles of metal are removed from the ground electrode each time the plug fires hence they gradually wear away. There is a misconception that a multi ground plug will produce mutiple sparks - this is not true, only the nearest electrode to the centre (i.e. currenty the longest) will spark, as that becomes worn, another electrode will become the longest and replace it as the sparking electrode.
Q9. Do my multi ground electrode plugs outperform single ground plugs?
A9. In most cases, no. The additional electrodes disturb the flow of gases around the spark plug tip and performance may even be reduced. In addition, for high performance applications the additional metal within the combustion chamber will retain more heat and may be more prone to detonation/pre ignition.-

Good to see you back Jason!
If you hunt around you will find some threads about this. Lets just say some of us have strong opinions about the directions BMW has taken. We have decided to not beat a dead horse anymore.-

I would normally change plugs in my spring maintenance. I did forget. Even have a box of the BKR7EIX plugs on the shelf.
This was totally my fault.
Between the bricked heart, subsequent broken ribs and all the carp floating round in my head I just plum forgot to take the plugs to Best Motors Werks.-

Good luck getting Gnat all fixed up!
By the way, the spark plug you want for the rebuild is NGK BKR7EIX (aka #2667). Coincidentally the same plug I ran in the Exige S, and in the turbo Miata.-

Damn Nate, sorry to hear that. Any idea what's going on? This is what, the second or third time?
Time to fix the bottom once and for all. Time for a Stroker.-
