2000 X has single-tipped platinum plugs supposedly good for about 60K, 02 got the double-tipped good for 100K or so. I replaced my platinums with NGK copper for about 1/6 the price. Copper provides a better spark, just lasts 1/2 as long as the single-tipped platinums. Which reminds me, I'm probably about due for another set now that I've hit 90K...
