this is my frist time try to take the spark plugs out of a 2 valve 1980 308gtsi the socket that i use is a 13/16 it does NOT FIT IN THE HOLE to get to the plug the OD is to big is this the corect 13/16 size to fit the plug.? anybody know the corect size socket to go in the hole + fit the plug????? do not have the tool kit that came with the car. any info?????. thanks.
On the 328, the plug socket size is 18mm. The OD of the tool kit socket is 1". For the front plugs you need to use just the right extension/socket combination or the tool kit wrench. It is a PIA at first, but once you get set-up it goes ok. Also, you should blow-out the plug holes before your remove the plugs; there can be some dirt in the deep cavities. Mark
mark the plug that go in this motor are champion # N7YC THE OD ON THIS PLUG IS 20.63 mm corner to corner 23.28 mm. the 18 mm will never fit it
On my '85 308, the 13/16 fits perfectly. The well and plug size must be different for the earlier years. In general, you'll be in good stead to get yourself the proper Ferrari plug socket. Not so much for the rear head, but it makes the job much, much easier for the front bank plugs. Best of luck.
Ria--on a different note, I tried to reach you re: oli lines ( I think it was you?). Anyway, the ones i recommended from Shako didn't work--after 5 min of idling, the line just let go at the fitting and my car, garage and I were rapidly doused with 8.5 qts of oil. I wound up getting OEM oil lines. Another thought re: the plug wrench-- a thin-walled socket will likely work for you. Just be sure of your plug size.

You will find that both of you are correct about plug sizes, on my 328 the original Champion plugs were the oddball 18 mm size. The plugs have been superceded by a new number which now has the standard small size hex which is 16 mm. So depending on what plugs you have you will need a 16 mm or 18 mm wrench size, could even be some manufacturers who use the common 21 mm size also. For the 328 the special Ferrari wrench fits the 18 mm size.
I use a normal Craftsman 13/16 socket with a universal and short ectension to get the forward plugs out of my 2V 1980 308GTSI, no problems at all.
the one i have is a 13/16 socket it is made for spark plugs and this is the one that will not fit. i will go out and try to get one normal 13/16 maybe the OD wall is thinner.
the 308 plugs should be 13/16--and the best tool I have found for removing them in the Porsche 911 tool--has a knuckle made into it. on a 328 you go down to the smaller 18mm plug --this one is hard to find but after trying about 12 stores I got lucky artAutozone
i try autozone no good there. the 13/16 socket i have that did not fit i finely put it on my lathe turn it to the size that will fit in the plug hole i did not want to do that but???
This real cheapie pressed metal spanner is just right for both banks of a 77 308. Don't know about yours though Ria
I have a whole drawer full of spark plug sockets from different tool kits purchased over the years. ALL of the 13/16 spark plug sockets - both cheap and expensive - fit just fine on a 1975 2V engine.
