tektrader can get the plugs, you can buy the whole coilpack loom with plugs from coz http://www.conceptzperformance.com this guy has heaps of stuff and is extremely quick postage.
I did find the plugs but in true aftermarket fashion. You could almost buy a car for the cost. They are something stupid like $30 each. I refused to buy them and must admit I have had so much else on I havent dug any further. You can buy em though. I think Bursons can order them in.
