When I got mine..440 source sent me a set of Champion RC12YC. But I too would like to know what other brands cross reference..like maybe Accel, NGK, or Autolite?

I'm running NGK FR5's. It's an extended tip, resistor plug in a fairly hot heat range. So far they are looking good (light tan color) being street driven with lots of idling and low speed cruising.

This site http://www.sparkplugs.com/ allows you to enter your part number and see all similar products by other manufactures.

NGK BCP5ES or BCP6ES. BCP6ES is a colder plug.

For street just use the same plugs that later model Mopar engines came with. It is just a basic 3/4 reach plug. Used in a billion applications including almost all aftermarket cylinder heads.

Just an FYI for everybody...

I put a set of NGKs (my preferred brand) in my stealths last week; the hex on the plug is partially obscured by the material of the cylinder head when the plug is seated. This makes it really easy for the socket to slip off when tightening 'em.

I hadn't noticed this initially, since I was staring straight at the ends of the plugs, reaching thru the fender.
