Bill-W are the B6S eqv to J6C or J8C….. isn’t J8C a hotter plug which is best for the 3-10hp range jw cd ad qd ?
anyway found a set of 4 on Amazon.ca for 18$CDN …..based on Bob-W experience
The B6S is about the same heat range as the J6C plugs while the B8S plug is a bit colder and is used in J4C applications. I don’t think NGK ever manufactured a hotter B4S plug so the B6S has to be used.
My local auto supply opens a 9:00 AM today so I’m going to see how many of these plugs they have left on their shelves. They usually have them in the ten packs so maybe I should load up if they still have them.
