according to champion the only difference in them is the hex size but compare them to make sure check the length if the electrode and thread length to be sure one is not longer the length from above the hex to wire the wire goes on does not really matter since it is out side the engine the length below does too long and you risk it hitting the piston and causing all sorts of really fun exciting chances of you getting to know your local tow truck operator or the opportunity to see how well your shoes are made. too short and performance can suffer because the spark wont happen in the center of the chamber causing an uneven burn across the piston and possibly allowing some fuel to be expelled unused out the tail pipe

If you never try to do it You will never be able to do it

I know they came with Champions but many of us have switched to NGK. As above, if threads and length are the same, it should be OK. One question. Is the porcelain the same for your plug wires. I have no idea as I have not seen the smaller one.
