Hi all, Happy New Year firstly. Right, I have a W208 230K (Engine is the M111.982) Spark Plugs last changed 07/2008 - Mileage at 72,000 This car uses Iridium plugs as standard... Mercedes EPC: A003 159 97 03 (NGK - IFR 6D10) NGK Partfinder for Cars & Light Commercial Vehicles - I was going to replace these today car now at 92,000 miles but I am told these are long life plugs and do not need to be replaced for quite a long time. (until I get to at least 110K) - I guess thats a good thing as the plugs are approx £10 each What do you guys think? I got one plug out but I have no idea...

Thanks all.
