    ^^^What he said. But, if you insist on aftermarket, Taylor Spiro Pros are a solid choice and are usually the same if not cheaper than OEM stuff. All you're really getting is the cool color, though.

    I heard the Taylor's come apart after a few R&R's but MSD's last. I recently had an ACDelco come apart after 2 plug changes so I went with the MSD Superconductors. And yes I pulled them by the boots lol.

    Thanks fellas. The wires can get real expensive. I'm not spending a $100 or more on wires. I'll let you know what I end up with.

    The MSD Superconducters were $77 but that's for the 2002 MY. I have a set of AC Delco 9748GG that I'll sell for $45 shipped but I'm not sure if they work for your application.
    Edit: cancel that; I just returned them to O'reiley's where I bought them for an $85 refund.

    I installed Taylor wires and NGK plugs haven't had any problems.

    I just replaced my plugs and wires a few days ago. The AC Delco wires were less than a year old but this was the 3rd plug change (I was testing heat ranges). I pulled the wires like you're supposed to all 3 times, by the boot. This time, 2 of the metal ends that click onto the plugs came off the wires and stayed on the plugs, rendering 2 wires useless. Last time, 1 did the same thing. I'll never buy AC Delco wires again. And they were $85 at the local O'Reilley's.

    Which version of AC Delco? They've got three levels of quality now, the part number will tell.
