i went to buy some ngk plugs at oreilly's today. they pulled out the laser platinums (ngk stock #2647) and wanted $10 each for them. that seemed steep. so i came back to this board to do a little more research on cheaper ngk plugs and did not find any specific answers. can i use the g power platinums (ngk stock #7090)? napa shows them online for $2.19.

any other suggestions with specific part numbers and estimated pricing greatly appreciated. <img src="/forums/images/graemlins/confused.gif" alt="" />
