Im gonna go ahead and give the Underdog Performance coil pack a try and I wanna go ahead and replace the plugs at the same time since I will be re gapping them anyways. What spark plugs do ya'll recommend? I remember hearin about NGK plugs once but usually what I have heard is motorcraft are the best.
Tell me what to get!
Thanks :)

 

I've run NGK, wasn't all that impressed, went back to Motorcraft. With a hotter ignition coil from what I understand copper core plugs are good for slightly better performance, but they only last about 30k miles.

 

Motorcraft FTW, I tried others they are not near as good as Motorcraft/Autolite Plugs.

 

Thanks Ya'll!! What do you think Zach..just the direct replacement? I was searchin and saw something about some fine wire ones or something

 

I've heard that the Motorcraft ones are the best for our application.

 

Direct replacement, Wayne sells them and you can get them at Wal-Mart

 

Alrighty sounds great thanks for all the help everybody

 

get Bausch platinum +4's they are awsome

 

x2

I've been running these forever and they work great.

 

The latest Motorcraft platinum plugs are called "Fine Wire" platinums.
Stay with these!

 

I just got baush platinum 2s installed and there awesome

 

lol get the fours they are the best ones they offer in the bausch plat. series

 

I am going to game the NGK iridiums we will see how they roll me

 

idk i like motorcraft...

 

Motorcraft plugs FTMFW!!!

 

Just one thing to notice. I picked a 2006 Ranger for this (for Rich's benefit), but if you look at the recommended plug from Bosch, NGK, or Denso, they recommend the SAME plug for the 2.3L, 3.0L, and 4.0L. Only Motorcraft recommends a
different P/N for the 2.3L, 3.0L, and 4.0L:
SP439 for 2.3L, SP432 for 3.0L, and SP412 for 4.0L

So, the heat range is optimized for each engine with Motorcraft, NOT the
aftermarket plugs!

I'm of the opinion "close enough" only counts in horseshoes and hand grenades, NOT spark plugs!!

 

That is a really good point I never noticed that before. Thanks man

 

That is actually a really good comparison there, shows they have just the right temps needed for what you need them for.. as opposed to having a 'generic' do it all for it.
