Don't bother with platinums. Just change out BKR6e plugs every 3-6k and you'll be good. They are dirt cheap and run the best.
Also, the best plugs for the car are NGK BKR7E's gapped at .032\" for unchipped and .028\" for chipped. They don't last as long since they're copper but at $2.39 a plug it's easy to afford to change them every other oil change. May not last the longest but they definitely run the best.
So I went with the ever popular BKR7E plugs gapped at .028\". I bought a spark plug gapper and verified the gap which is a good thing because the BKR7E's come pre-gapped at .033\".
i like the way it runs str8 out of the box b/c ngk says not to gap them
My old GLX didn't like anything but NGK coppers.
i have run the ngk v-power plugs the past couple of years with great results. part number r5671a-9
If you like Bosch plugs, use a 7 heat range. The stock 8 is fine for quick in-town trips at stock <10:1 compression. Older 8v's used 7 with the same combustion chamber and lower compression, with 0.032" gap stock. At 11:1 with a big cam and the same ignition mods, an NGK tech told me to run colder plugs (Bosch 6 equivalent, NGK 7) at 0.035" gap. He sent me a box of NGK race plugs, I gapped them, and my car ran sooooo much nicer. I was using Bosch W7DC and W7DTC (even worse) before.
so right now I'm using ngk bkr7e for a turbo application. i am pretty happy with them.
Mine popped up with the NGK's all i did is tighten the spark plug a little more and it stopped.
NGK Iridiums.... Not right for the ABA, and really a waste of money unless you are running a hopped up ignition, anyway.
