Replaces the old Champion J-8.
Replaces the obsolete J-8 plug in vintage small engines.
Most Liked Negative Review
Items good Service wasn't.
The plugs were great . I ordered online the night before I went to pick them up. It said they would be ready to pickup in 30 minutes that night, but I went in the next morning and had to wait on them to pull my online order . That added 7 minutes to my time in the store. Don't say it will be ready to pickup if your going to pull it when I get there. If I would have known that I could have went to store got my plugs and paid. then left. That what online ordered is about shop, pay and pickup .
