Champion RDJ8J: Is this a resistor type plug?
 

Folks,

The spark plug on my petrol engine is a Champion RDJ8J. I have very little experience with these engines, aside from the information I glean off these forums. I would like to know if this one is a resistor type plug, or I should change it. What is a suitable equivalent?

Thanks

Champion RDJ8J equivalent is the NGK BMR6F

Both are resistor plugs. Drop in replacements for the difficult to source BRISK UR17 plug as supplied with some of the MVVS range.

The "R" in the plug designator represents resistor type.

That was a nice bit of information regarding the MVVS Brisk plug cross over.

Another equivalent from Champion is the RCJ6Y

Nope...RDJ plugs are taper seat, RCJ plugs have a gasket..
