Hi,
I've just ordered a set of NGK plugs from ebay for the bargain price of 32.38. They are listed as being for a C55 AMG (so there are 16) but I believe they are the ones for the NA 3.2

NGK SP PLUGS x 16 MERC BENZ C55 AMG 5.4 02/04- IFR6D10 on eBay (end time 10-Feb-10 05:59:18 GMT)


Just thought I'd share....

I bought a set of these, which arrived this morning. An absolute bargain and well worth it for a routine change for anyone with a 4/5 year old Crossfire like mine!

Regards, Andy.

 

Postal service must be better where you are, I'm still waiting

I ordered mine on Tuesday. They were only sent via normal post and were in a cube which wouldn't go through the letterbox, so the postman left them on the doorstep. Might be worth checking that they've been sent? I've got 4 going spare!!!
