3.9 V8 disco runing lpg

evening all im going to replace my spark plugs and was wondering what plugs you use or think are good quality i have been looking at bosch supa 4's a friend recomended champions to me and said thats what it should have..............they were always the **** plugs when i was a kid and the 1st thing we used to do was fit ngk's on the bikes

NO don't do it . Experiance has shown , only use single prong plug's .The gas needs a good spark only provided by singles , multi prong prugs although listed by the plug company were never a standard fitment by god ,( sorry Land Rover ) , best make I have used is NGK , other's may say different , go up 1 heat rating from standard though . Hope this helps , if not I may have started another argument .

nice i very nearly made a costly mistake, armed with this i shall get some single point plugs
