spark plugs - tony
About 3 weeks ago one of the Denso Spark Plugs fitted in my Toyota Carina 2 3 S-FE engine exploded. The centre porcelain core and centre electrode parted company from the screwed part of the plug which remained in place in the cylinder head. I have e-mailed Denso Europe and Japan but have not had the courtesy of a reply. The plug had only been in place 6 months. Any ideas or similar experiences?

It happens, occasionally. Probably will never happen again.

But I can affirm it's surprising when it blows past your thigh!

If you have only one pot, carry a spare.

Mate of mine's brother had a knackered plug fire clean through the bonnet of his recently polished Polo - Not a happy man!

It's usually the thread in the head that strips, letting the plug fire out, rather than the porcelain exploding, in my experience. Still makes you jump though.

If you accidently drop a spark plug onto something hard,a garage floor being an example,scrapping it will avoid you having this experience.
I have some old,very old,dismantle-able spark plugs here,they are for vintage boat engines.They will withstand nuclear attack.
