Can't remember the number but I used NGK in my D17 (long reach so number wouldn't be right anyhow) one year and within a month I had to replace 3 of the 4 plugs.

I just read the reviews on E3 plugs. Some positive, some negative. Overall a mixed bag. I see they give a 5 year, 100,000 mile warranty, which is what you'd expect from any premium plug. No lifetime warranty. If the plug fouls it's going to misfire. I don't care what the warranty states. Tell us what they cost. Meanwhile I'll stick with NGKs.
