Cosworth BDG Spark plug type and gap

[Paul S]

Does anyone have a recommendation for spark plugs for a BDG and what the gap should be set to??? I have Autolite plugs in now, part number 4302 and a .65 gap.

Original paperwork calls for a Champion N54R but does not note a gap setting...

Thanks!!!

I run a Hart 420R and have found the Champion plugs are best, added bonus no gapping required

my 420R uses the same fuel cam as the BDG, we are both 2 litre so should be very similar burn rate

Be very careful about trusting anything from BAT. The vast majority of the posters know little of what they are discussing. A simple call to Jennings (435-843-2815) and Cliff will answer your questions.

Agreed. I was referring to the 15 pages of info from Jennings posted among the photos.
