View Full Version : Bosch Super Plus Spark Plugs
I have just bought these from gsf, but im having doubts if they are the correct plug for the Williams.
They have +8 on the side of the box with code FR7DC+ and they say the gap is 0.90mm and the lead thickness 060.
Are they the correct plugs?
Gap shouyld be 0.8mm shouldn't it?
Just go for some single NGK jobbies.
wrong set mate, ive got a set of bosch super 4 plugs infront of me now and FR56 is stamped on the side of the plug, gap is 0.8 aswell.
bosch super 4's are the last thing you want to fit.
Get NGK's.
