Hi. I just went to clean my plugs to see if my retuning had made the car run a little leaner and had a look in the Haynes manual for the correct gap.
When I finally found it I noticed that the manual says there are two different plug specs, one for 1975 ( which mine is ) and one for the rest. It seems I should be running a Bosch 175M30 or equivalent, so down here a Champion N9YC which I presume is slightly longer. I have searched for a thread on this but can't find anything. Any ideas? And do you think it will be ok to fit a N9YC/ Thanks Richard |
