Which Spark Plugs?
Posted by Dave Merrick On 2011/4/15 10:25:04
So my '51 327 has a '48 head on it that takes 10mm plugs.
When I got the car it had Champion UY6 installed.
I cross-referenced this over to an AC M8 (Which is a marine plug) and the car ran terrible. Tons of carbon on the plugs.
I'm looking at the manual for a '48 and they specify Champion Y4A. Is that what I should be using?
