Leave them on bud. My experience with this is that they are better off left on as the heat from the alloy block is alot hotter then most realise under the hood and it can play havoc if you don't.speed_demon_freak said:When you guy changed your spark plugs, did you leave the heat protector on or did you remove it?
Without a doubt you know more about auto mechanics than I do. Hell, my DOG knows more about it than I do. But I can honestly say upgrading the plugs and wires made a NOTICEABLE difference in performance. That, IMHO, is the key to ANY upgrade. The change has to be noticeable.Rocket said:I'm not understanding why everyone is changing their spark plugs. They are not a performance product, but rather a maintance item. I doubt anyone has had any failures yet. Its a Snake-Oil idea unless you are changing the gap for N2O or something like that.
FLORIT said:The stock heat shields would not fit over my Taylor 10.4mm wires, so I left them off. I know of at least one other member who left his off, too. I have carefully inspected the wires after putting several hundred miles on the car and there is no evidence of heat related damage. They still look great. If, however, you see this as a serious risk, let me know and I will take appropriate measures.
