C2 '66 BB plugs

[Tom Merkel]

Recommendations, please for a '66 BB 425hp spark plugs. I believe the stock ones were the AC 43/44/45 series, but they're not available here. Champs or other are OK.

Thanks.

get AC R 45XLS or equivalent these are extended tip plugs and will last longer than the std tip plugs.

I'm pretty sure the R43 is still available, at least as of a couple of months ago. The R44XLS were also, and that is slightly hotter than the 43 and better at around town driving.

Take a clue from what you have found, they aren't long for this world, so when you pick up a pack, pick up a couple extras.

Check e Bay I picked up a set of 43N plugs for a 66 427/390 for $25, they are in the orignal boxes and in excellent (unused) cond. I don't know if the 425 used the same.
