NGK spark plugs breaking.

Thanks, Dan. I know you recommend going with the NGK ZFR5N plugs for my stock 1974 slant, but if you did go to a Champion plug, which one would you use? I don't think Champion makes the N14Y any more. Thanks!

RC14YC is the same plug as the N14. The only difference is the N plug had a 13/16 hex and the C plug has a 5/8 hex. The 5/8 hex is much nicer.

Edit: I’ve seen as many NGK and Autolites with bent ground wires, off set insulators and everything else.

I’ve used and still do use Champions in virtually everything I tune. They are easier to read.

So this bullshit that NGK’s are a step up from anything is nonsense.

I’ve pulled and replaced more NGK and Autolite plugs and made more power so many times I can’t count.
