Looking For Colder HD Spark plug
I am running HD 5R6A plugs in front and back cylinder.
I want to run a colder plug in the back. Does HD make one and what is the model number |

Re: Looking For Colder HD Spark plug
You can find a number of manufacturers if you cross that plug, but I wouldn't do that. Keep them both the same plug.
Crossed into a champ plug that would be RN12YC for the stock plug. Trying to locate my cross for the champs. I believe the champ number goes lower for a cooler plug.

This is were a lot of the problems with Hd come from mixing and matching the wrong parts for them.

Re: Looking For Colder HD Spark plug
I dont want to cross or miss-match plugs.
Just wanted to know if HD made a plug colder than 5R6A. I will talk to my dealer. Thanks guys |

Re: Looking For Colder HD Spark plug
Nothing to be gained by going to a colder plug. If you are thinking it will make a difference in the engine temp, it wouldn't be measurable and the engine will not run as good as with the stock plug. Generally the only reason for a colder plug is to eliminate a pinging problem from other problems.
