Yea, they must be a little more efficient in the city, - a better burn.

 

If this means anything - when you buy a complete ignition upgrade kit from Troyer, you get Denso Iridiums. Otherwise, stick with the OEM Motorcraft fine wire platinums.

 

well i think im going to look into denso...decided since i dont have to replace these that often might as well spend some extra money and get it done right....

 

I tried the E3's and while i noticed a few SMALL changes, they had so many problems i got tired of replacing them. advance is the only place near me that carries them and they usually only carry 3. they keep failing. i originally bought 6 but through returns have replaced all of them. some twice. FWIW
