which plug would be better in the 5.4 ngk or autolite...im thinking on one of these but not sure which one yet..the ngk plug number i am thinking on going with is TR55IX or the autolite app 103...has anyone tryed them E3 Spark Plugs how they any good??

 

The general consenus on this forum is Autolite or Motorcraft. Anything else seems to produce recurring problems.

You may want to read the sticky thread at the top of this forum about changing plugs. A lot of good information in there from Racerguy and other that have replied.

 

I can vouch for the motorcrafts, I did a plug change over a year ago and went with the bosch platinums, within a week I replaced them again with OEM motorcraft plugs, ran like piece of **** with the bosch, seems these modular V8's are sensitive to aftermarket plugs.

 

And you can buy OEM Motorcraft plugs AGSF22FSMF4 from me if you like FTE $ 4.86ea
List $10.95 ea


Thanks Ed

 

yeah i called the ford store here in town and they told me 10.95 but they was out of them..im going with the autolites..thanks guys

 

Has anybody out there used the Denso Iridium plugs sold on the troyer performance website?

 

From what I remember those Denso plugs are a hotter plug and are meant to go with the package that they offer, if you have a stock configuration with a few mods the MC will do everything and more.

 

Motorcraft!!!!!!!!!!!
