I dont know the neck of the plug wont fit cobra heads. It's o.k. though because I remembered I had a set of NGK iridiums from my 96 cobra out in my parts bin and they are designed to fit the 95 cobra too. No sense letting $70 worth of plugs go to waste. Got lucky.
The stock E7TE head uses the Autolite 25's or one colder in the 24's. The GT40 head that is on the cobra uses the autolite 765 or one colder in the 764.
