Champion J6J equivalent; 1956 Fastwin 15HP

[rjezuit]

Went to 3 places today looking for J6J plugs for my motor. Struck out at all 3 places. Does anyone have a recommendation for a good equivalent plug? Thanks, Rick

Think J6C is what your looking for now Champion does not make the J6J anymore . Im sure the experts here will fill you in
I have a 1955 15 hp Fastwin and it has the J6C 's in it and it runs good

Two out of the 3 that I went to offered Autolite instead of the Champions and the 3rd offered NGK. Any difference? Rick

I still prefer Champion, and my least favorite is NGK

Comparing Champion, NGK, Autolite is a lot like comparing Chevy motors with Buick and Olds motors. Don't sweat the difference, especially in your motor.

Originally Champion J6J or Autolite A3X were specified.

J6C , gapped at 0.030", are the currently recommended plugs and the modern equivalent of J6J ... copper cored and all that stuff

A3X I believe are still available

B6S are the nearest equivalent NGK plugs

You might get lucky, but I betcha' that motor won't like the the NGK's. Save yourself the headache and find the Champions. IMHO..........Champion, Autolite, NGK.....like first, second, and third place finish.....

Couldn't find the Champions but picked up some Autolite 303's. Will see this weekend. Rick

Are they suitable ? I came up with 306 from an applications list?

303 is a heat range 3 plug. The recommended J6C are heat range 6

The Autolite website that does cross references shows them as direct replacement for the J6J and J6C. Rick
