I installed a pair of these plugs in the Atlas today and they give a noticeable improvement in performance. Use only after the carburetion is dialed in because they are $10 apiece. Also goes by the number 5307.

Is that a noticeable improvement over other Iridiums (eg NGK) or over standard plugs?

That's a nice plug for the Norton and EI.

Summit Racing sells those ND plugs for $7.99. Shipping would probably make them $10 though, unless you could come up with a $99 order, which would ship for free.

I have a standard Boyer about 20 years old.
I was using the usual BP7ES plugs. No idea how the Denso plug compares with other iridium plugs.

i'm sure this has been covered many times, so FWIW, if using iridium, DO NOT buy them off fleabay UNLESS you know the seller. hit or miss on whether you'll be getting genuine iridium plugs - many knock-off coming out of china. if the price is too good, most likely they are knock-off plugs.
