Why? Just wondering. I mean, if they are heat shields, then they are there to keep heat off something that shouldn't be heated, right? Or no and they are there just because? (not meaning to sound like a smartass, but don't feel like rewording)
Spark Plug Heat Shield Removal
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?
