My euro engine has a label on it with spark plug rec.
Says
Bosch W7D
Seems the US engine takes bosch W8D
I ordered
NGK BP5ES
I found a cross ref table
http://www.spark-plugs.co.uk/pages/technical/boschw5a-y6dc.htm
says the bosch W7D translates into a different NGK BP6ES
It would seem the NKG equiv to the bosch is the 6ES
Will the 5ES not work as well?
I wonder if Rusty will exchange them for correct part
Really is quite hard to buy Euro parts even if you add a note that the engine is a Euro & if any parts are different to update..
I would assume its best to install the recommended plug...
Should I return them/ get correct...is there big diff in these plugs?
Does my engine run w a cooler plug?
Seems higher NGK number is cooler

Would my engine at 196K be ok or better w a hotter plug?
Thanks
