I think that you're referring to the Bosch Platinums plus4...I've heard nothing but bad news about them. For plugs, NGK tr55's are great and inexpensive, and NGK, AC Delco, and Denso all make quality iridium plugs, bu they're very pricey. As far as wires go, I've had good luck with my MSD's, but the stockers are more than adequate. Don't have any personal experience with the Taylors, but folks around here who have used them seem to like em.
