Yes you have to change them to non-platinum and gap them in this range .32-.35

autolite 103's
Don't run any 2 or 4 prong bosch style plugs or other bs just stick with a standard autolite or motorcraft plug as these tend to cause missing, detonation and things along those lines

why wouldn't you recommend platinum's on a blown car, even if they are supposed to be factory equipped??? I run TR7 ix's(two heat ranges colder, gapped at .35, iridium which is similar but a harder alloy to platinum) and the car picked up a lot of hp (14 rwhp at 6000) on the top end because the autolites would start to misfire after 5500 rpm(at least that was what powertrain dynamics was telling me). I mean, my car(91 GT) is not factory equipped with platinum's but the 2003 is. Just would like your input

Well pretty much every car that showed up on the dyno I have seen with platinums pinged like mad at any plug gap. The tip I guess is more prone to do this I guess. 9 times out of 10 when a car would come in with a new supercharger kit installed with the factory platinums still in it pinged, we removed them for the non-platinums and the problem went away. I know when the iridiums came out they were supposed to be the next best thing to sliced bread but we tried them as well on many blown cars of which pinged or had a miss right after they went in. Your case is one of about 3 that I know that got away with that style plug.

We also tried a colder heat range platinum with the same results.

FWIW, my turbocharged import (240sx w/sr20det) hates platinums. Every shop has said platinums are too hot, which is why on any forced induction
uses regulars or on imports, 2-stage colder iridiums. Stick with the autolites, dont blow up your engine sticking platinums in your motor. Also i know this works for turbos, but working with a colder plug can actually allow you more room for boost, just a thought. Stay away from the gimmicks, Platinum is ok for n/a but is really for people who cant change their plugs as often, ie "the basic consumer".
