Quick question for the gang - what spark plug would you recommend for a BN2/100M ? Know Champion NA8 was specified by Healey but imagine that is not even available anymore. Can get Autolite AP63 locally and Moss sells a Champion specifically for the 100M but do not list a model number.
Thanks,
Mike
 
I like Bosh Platinum plugs type WR7DP

That is the same plug I used on my 100 after I rebuilt the motor to M spec. I have used Bosch Platinum on other cars as well in a couple cases where I was having fouling and misfire issues with the prior plugs and the Bosch seemed to clear everything up.
