Ok I found some autolite plugs for 2 a piece on eBay, there compatibility thing says the plugs are the same me the 03 3.1 and 98 3.8 gtp,does that sound right?,also when I find wires for the gtp the compatibility thing says 99 and up,I thought 97-03 wires would be the same,figured they'd be the same for the 3.1,anybody know?,thanks
