I'm sorry what are you talking about wrong plugs?
The plugs that were taken out of it are NGK BKR6EGP G-Power Platinums. The link you provided to the ECS tuning page doesn't give any information that the wrong plugs were used ...unless you're going by the picture they provided (which I seriously hope you're not
) . The second link to the pdf by NGK talks about the fact that VW made several variations of its 2.0L 8v engine. Although they pretty much look the same on the outside they do use different parts a lot of the time (I know I own two other MK4's with different 2.0 variations). To avoid getting it wrong each engine has a 3-digit code to tell the owner which he or she has (In my first post I stated I have the AEG engine). So unless NGK, and my autoparts guy got it wrong I should be using NGK BKR6EGP's.
