DirtyComanche Posted April 28, 2007 Share Posted April 28, 2007 Champion truck plugs. The cheap ones. Everything else is a waste of money. Link to comment Share on other sites More sharing options...

JohnQ Posted April 29, 2007 Share Posted April 29, 2007 I'm running an Accel tune up kit I got from 4wd.com. No complaints here. It came with new dist. cap, rotor, 8mm wires and plugs for around $50. Link to comment Share on other sites More sharing options...
DirtyComanche Posted April 29, 2007 Share Posted April 29, 2007 why not The 4.0 is rather old technology when it comes to cylinder head design (60s), and is also rather low compression, and doesn't rev very high. Sure, you can use an expensive plug, but you won't see a difference. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted April 29, 2007 Share Posted April 29, 2007 I agree with Dirty, Save your money on them platnum plugs!!! YOU don't WANT/NEED THEM!!! Champions are the way to go for these older engines!!! As for the cap aabout any better brand will do you fine. Personally, I prefer the NAPA line. Its got brass contacts and has worked well for me for many many years. Wires, again any name brand will suffice. CW Link to comment Share on other sites More sharing options...
JeepcoMJ Posted April 29, 2007 Share Posted April 29, 2007 make sure the plugs are long enough thread for the 4.0...SPECIFY what vehicle they are for when you buy them...one of my trucks ran like crap when i got it with them 4 prong plugs...they weren't long enough, and weren't even tightend down (3 were not even in threaded in Link to comment Share on other sites More sharing options...
