DISA visual inspection is not enough.

You will likely need a DISA O-ring, but you should read the first link below in my signature.

If you only have misfires at cold start or at idle, not likely you have serious secondary ignition problems, likely lean air/fuel mixture issues.

That being said, no substitute for fresh plugs and coil boots to start out with, then move on to the simple broken plastic and rotten rubber parts.
