My '84 2.8L V6 calls for an AC R43TS.
However in my experience the R44T or R45T are better choices (heat range) for my
old 1970 SBC 350. I don't get too
caught up in brands but do like to choose plugs based on heat range. I'm
wondering if the SAME is true for the 84 2.8L
V6??? E.g. Am considering stepping up to an R44TS for example in the V6. The car
is predominately driven in highway
cruising (almost no stop and go city driving).
Anybody looked closely at heat ranges for the V6s or considered an R44TS or
