im just curious about any long term ill effects on removing those spark plug heat shields on a 3.9 v6. im going to be installing the napa premium wires and just afraid off cooking the boots, thats all. Is it worth removing these things?

No you do not need the shields. Mine hit the trash 8 years ago. The make changing the plugs a lot harder and trap dirt around the plugs. Grab the shield next to the split and twist in.
