Hi

Is it NGK Ruthenium and if so are there a special product number that will fit the 413 engine?

Thanks
Allan

Best plugs by far today are NGK rhodium tips . Very wide heat range , last 100 k .+ on new cars . A little pricey but worth every cent

Hello everyone,

I was wondering what people’s recommendation on spark plugs are for the 413? I have the charts and know what the books say. I can also tell you that on my 1940’s flatheads that they run better with plugs that deviate from the direct cross references.

In addition, I have found out that the plug recommendation for city stop and go versus road trip plugs can be different. Since I have not run a V8 in 20 or more years and with all the gas formulation changes, I wanted to ask the group what they have found works well with todays gas in the RB 413 Wedge head engines.

Thank you, James
