Wich is the better performance spark plug for a 454 mag EFI the AC Delco MR43T or the MR43TS. The MR43T is a standard nose plug and TS is a projectid tip. Please help. Also is the NGK V power a good performance plug.
Thanks Bill

Donzi22zx....One other plug you might want to try (which is like the MR43T) is the NGK-BR6FS. I've just put a set in on one of the engines (just by chance the place didnt have the others), and, I must say the NGK's are pretty darn good so far. I do not remember the motors starting up quite that fast before.

The M does stand for marine. Both plugs perform exactly the same but the marine version, which is always more expensive, has a rust proof metal case. I use the R43TS plugs and change them every year and don't have a problem with them rusting. I guess if you change plugs every 2 or 3 years you might want to use the marine plugs. It's no fun trying to get a broken plug out of a head. Sometimes the cylinder head has to be removed to do it.
