For an S2, and I don't mean heat range, electrode length, gap, etc. I mean, I've got 19mm and 24mm deep sockets, and the plugs are somewhere in between.

I only want to make one trip to Sears - what size do I need to buy?

Thanks,
Scott

13/16" is standard size

Be sure to get a proper spark plug socket. It will have a foam cylinder inside it to gently grip the ceramic insulator of the spark plug so you can pull it out of the hole. 3/8" drive is desirable.

foam? mine are rubber insert.

Scott at Team Harco

Foam rubber. It needs to have some give to provide some compressive force on the insulator.

ah. never paid too much attention to the thing inside heh. has always just worked

13/16" eh? My standard (non-spark plug specific) 3/8" drive deep socket won't fit into the spark plug well in the head, so maybe a 13/16" spark plug socket has thinner walls? I'll have a look-see at Sears today - thanks for the responses.

So, which one is it??? I'm heading to Sears tomorrow myself... Is it a 13/16 or 3/8?

He means 3/8" drive, not socket size.

Standard spark plugs are either 5/8" or 13/16". In the case of the 944, it is 13/16"
