My 2003 E85 3.0 is listed as using NGK BKR6EQUP (3199) plugs.
On searching for these on the web there appears to be two types. One with a single electrode and one with 4. I'm assuming that I need the 4 electrode variety?
I have looked at those (1208) but they don't appear to be a straight replacement for my car. I've checked it on the NGK checker too and they are not listed for mine!
