Re: Another spark plug question

Ayuh,.... Other than the alloy of the body, it's the Same plug,....
The R43T might rust, but it's the same plug,

I know that, but I wouldn't want them in my boat! I bought a boat yrs ago with a Ford 302/188hp Merc. got all the spark plugs out but one, it was not plated, & so rusted, and in such a tight angled spot, I had to take the head off!
Even before I got to use the boat!

Never again black spark plugs in a marine engine

I know my old 96' Chevy S-10 had the new improved Vortec V6, but was totaled, so I picked up a nice 95' S-10 V6, but both seem to have the same amount of power

Yes, That's a short thread plug hole. the AC R45T are a popular marine plug,

Oops! Just a typo, forgot to add the M, as in AC MR45T, although the AC MR43T is probably more popular, because the MR45T is a hotter plug, only to be used if needed, or required by the engines specs.

MR43T, MR44T, MR41T (not sure about the availbility anymore of the last one) are the marine plugs in that series. No MR45T.
