    Spark Plug Heat Shields

    As part of my header install I replaced the spark plugs and bought MSD wires. Is it necessary to invest in a set of heat sleeves for the new wires? I saw a recent thread where the metal shields were apparently swapped over to the new wires, but this only covers the boot. What's recommended?

    I really like my heat sleeves, just a nice added security.

    Mine has these too with springs connected to them. My stock manis are not loggers they actually have a tube for each port and those areas gets HOT. I wound use them imho.. My after market gaskets are bent steel with a roughly 2 inch shied built/bent into them but I will still use the metal boot collers. Just my .02..

    Lil extra protection never hurts. I personaly removed the stock head shields and used some Accel Kevlar heat shields.
    You can pick them up at most parts stores for like 50 bucks or so....

    Never had a problem running MSD wires and no shields. I don't care to wrap metal around my plug wire boots...

    Thanks for the replies! I am also uncertain about the stock pieces, especially as they only protect the boot. On the way home from work tonight I stopped and picked up a set of DEI sleeves and will see how they fit.

    I do not have headers, and when I replaced my stock wires I kept the stock heat shields, and added aftermarket kevlar heat shields that wrap around the lower part of the wire.

    An ounce of prevention is worth a pound of cure.

    i kept the shields, and will probably get the shields that cover the wire also. its kinda like that drunk chick at a party that looks 18 and says shes a virgin, but you still want her to pass out first and use a condom just incase.
