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?

Did mine today, took a while on the first two and got a blister from twisting, metal is pretty strong to bend. After those two, the rest came out like a breeze.

A tip: Take pliers and insert them deep on one side of the slit, close to the plug and then bend down once and hard. Then twist and pull a little and it will slip right out!
Use the tip I provided and they will come out quick, no need to remove the plugs.
