Default Spark Plugs

What spark plugs should I use in my 87 454 mag? I was thinking about going to the AC Rapid Fire's.
Thanks
Dan

The ECM in my boat didn't like split-fires for some reason ..just an fyi

Personally I like NGK's best....they just seem to allow the engines to idle better.

I did not know the MR43TS's weren't available. I did know that the Rapid Fires were a cross ref for them.

Rapid Fires are good, but pricey if you don't need them.
You could just run the automotive version R43TS. If you change them every year, they will be fine. they aren't SS and will rust slightly.

MR43T MR43TS
I have to wonder if it is a generic picture or if they changed them from the stainless version?
