Picked up six NKG Iridium plugs #018-4750-0

Just wanted to confirm I had the right ones.
And also ask what's the gap is supposted to be for my 2007 3.7L V6

I was also reading the back of the package and it says
"Important Do Not adjust spark plug gap due to extremely fine center electrode.
I assume I don't need to adjust the gap but want to double check the gap and make sure this is all good before I go ahead and install.

Thanks

 

ZFR6F-11G
Gap (0.042 in.)

 

ZFR6FIX-11 is the number on the pack.

The gap tool I have doesn't have 0.042
closest I have is 0.044 which is a tiny bit big so your prob right on. but I also checked the NGK site and they say 0.044

I'm sure your right though.

 

I posted something but changed my mind about this certain type of plug.. Cya Slick

 

I've been through every thread on spark plugs I could find, there's not a lot of info on the 3.7L engines,
I'm going to look under the hood this afternoon to see what it recommends.

any other input?

 

Don't forget to shoot some compressed air into the holes before you remove the plugs from the motor or else you might get dirt in the engine.

 

i always run the autolite 3922 plugs, the nitros system likes these plugs, but before going all out on the motor the autolite 3923 plugs were great. they are one heat range cooler than stock champions

 

I'm running NGK BKR7E, stock# 4644 in my blown 4.7L. They are one heat range colder than stock.

 

I also have a queston about spark plugs... There are E3.64 and E3.48 by e3 diamnond fire. Whats the diffrence and do they realy add power??

 

From what I've heard those E3's work best with a higher octane fuel. not sure on the diff between the two models
