Time for Plus...and maybe wires

[not enuf toys]

Hey guys, looking for some help. Its time to change the plugs on my 5.7lx. Currently it has the MR43t delco's in it and the manufacture book calls for that or Champion (which I wont do) or the NGK (sorry I forget the number)

question is, which one do you prefer and why?

Doesn't matter, as long as it's not chumps...

NGK - BR6FS

I prefer NKG, easier for me to get...

AC or NGK are equal as far as I can tell. AC is GM OEM plug.
Champions shouldn't even be mentioned or allowed near an IO engine.

thanks guys, are they the same heat rating?

I have always stuck with delco for GM cars (or boat motors in this case) and NGK for Japanese cars and motorcycles. Probably not a big difference but definitely never champion.

They are direct cross reference by Mercruser, so what do you think?

haha funny
what I think and the truth are two different things ~ and as for what GM does, well that's what ever the hell they want!
