I have a 01 Screw. I was just wandering what would be the best spark plugs to buy. I have installed a K&N FIPK and a Borla Exhaust. Planning on more mods. Anyway what's the spark plug of choice amongst you guys. Thanks for the help.

 

I'm sure if you search here you will find a lot of opinions. It seems like most like Motorcraft or Autolites. I hear the bosch don't work to well.

 

Factory Motorcraft! :santa:

 

I agree myself the bosch plugs suck, I have tried them and the electrodes seem to burn up in fuel injected vehicles.
I always use autolite or Motorcraft they both are about the same thing, I also like NGK's.

 

I never was very happy with the stock Motorcraft plugs. Only the electrode is platinum plated, and the rest of the plug will rust/corrode into dust. Not exactly the hottest plug for cold weather starting either.


Had I taken the advice from the guys on this board, I would have never tried the $2 Bosch Platniums. But, I took the advice of the local Ford racing teams and went went the Bosch plugs. The truck didn't run this good new, and it starts instantly even in sub-zero weather. They also seem to keep the deposits down in the EGR system as compared to the Motorcraft plugs.

 

DENSO IRIDIUMs are working well for me

 

DENSO IRIDIUMs i like these also only had them on for like 1000 miles but they are great idles smooth as glass and i would swear that my throttle response has emproved

 

What Ford racing teams are you referring to?Do they have an e-mail address? I would like to know how they get Bosch plugs to perform so well in there Ford engines! Maybe you can have them contact me.Send me a private message for my e-mail address.
