[bordin34]

What spark plugs does everybody have in their 318. Can somebody tell me a part number?

[Nacho-RT74]

Champion RN14YC is what haynes manual says

i cant tell ya the part number since its been years since i worked on a small block, but i just went to the parts store and asked for the plug for one and got champions. my mopars like champion plugs and NGK plugs. and they dont care for many of the others.

you can run the RV14YC I think is the # with the smaller 5/8 " socket , sometimes it will clear the headers better

The RC type plugs use the 5/8th size sockets.

Thanks I'm going to get ones with the normal size socket.
