Sparkplug strangeness

[paultakata]

I just changed the plugs on my FD for the first time yesterday ("just" meaning 3 hours of mucking about under the bonnet of course) and was a bit surprised at what was in there. The leading plugs were BUR7EQP, which seems correct, but the trailing plugs were BUR7EQ  :confused:  not even the platinum ones!

Does anyone have any idea why someone would do this to a stock engine? The car only has a catback exhaust, so I wouldn\'t have thought changing from the recommended 7\'s and 9\'s would be necessary?

Incidentally, I have replaced the plugs with 7P\'s in leading and 9P\'s in trailing. I got them from http://www.sparkplugs.com/ for about £32 including shipping, and the shipping was about £15 of that!

The platinum ones just seem to last a bit longer. But you should have 7\'s and 9\'s in a stock car. or just stick 9\'s in
