Certainly the long reach socket that is in the tool kit(yours is missing) will work, My mechanic said just use a socket for HEMI heads. For what it worth you can probably get one from G & R imports. The bumps in the spark plug hole threw me for a loop the first time. But I scrounged arround all my trucks and came up with a socket in one of the tool kits. LOL
