E3 spark plugs, are they any good.

 

ive heard their nothing special. stick with motorcraft

 

What about bosch platinum quads?

I never had any issues with them yet...

 

Just replaced mine.......stuck with Motorcrafts. Just heard too much crap going wrong with other brands.

 

ive always heard they were ****, but this guy i work with swears by them, hes used them for like 120k miles so i dont know what to think.

 

I'd stick wif the Motocraft or Autolites.

 

how do you know when your spark plugs need to be changed?? Is it hard to change them yourself?

 

I've used the Bosch Platinum Quads and they have always done me good.

 

i put motorcraft platinums in

changing sparkplugs while incoherently drunk is just as challenging as it may sound

 

Yea they run nice in my ride, changed them out twice in 90k miles with no issues.

They give a lil more power too :)

 

Stay with the Motorcraft double platinums, or the fine-wire platinums.

If you aren't mis-firing, no power is to be gained from the type of plug used.
Bosch caused a misfire problem in my 3.0L, and there have been many other complaints from Bosch plugs posted. Stay with Motorcraft, you will get the correct heat range, and they will last the longest!

 

What do you all know about NGK irridium plugs that is what I am thinkin on using
