Can someone tell me a 5/8” replacement Champion plug for a RCJ6y? This is a 3/4” plug and the booton my ignition is 5/8”.

Google is your friend, there are 52 possibilities, if running on a mag make sure to use a resistor type plug.

I think it is better to replace the boot.

NGK BPMR6F if your engine will accept a tapered seat plug .... and most will. There is a washered equivalent but I don't have that #. These plugs fit the 5/8" caps perfectly. Ralph Cunningham put me onto these years ago and I never used a 3/4" plug again.

Edit: NGK BPMR6A is washered version.
