Plug Gap
 

I just ordered the McCarville tune up kit for my 91GT's long-overdue tune-up... and I'm embarrassed to say it, but I can't remember what I should gap the plugs to! I'm running a bone stock motor- I do, however, have the Crane PS-91 coil, which would lead me to believe I can open up that gap a little more. What do you guys recommend?

I shouldn't post this, because I am not completely sure, but seem to remember around a .052-.054 ? (at least for my 95)

had to edit, forgot the '0' infront...

Check your underhood sticker for the factory specs, but it will likely say .044". Don't go past .050".

Take care,
