So I'm ordering a CAI/Tuner, but as I was doing that I noticed that a lot of people were purchasing new ignition components as well.Reviews saying big improvemnts in throttle response,idle, and even mpg from upgrading to performance spark plugs,plug wires, and a coil pack. Could do all of this for about 200 from AM.com

Has anyone else done this or know if its worth it???

 

Anyone?

 

Check out this thread:

coil

 

Thanks!

 

The stock coil pack is fine, and the only problems I have heard are from people who switched to the screamin demon and granatelli coil packs.

As far as plugs, the stock autolite 5143's are great plugs. No need to spend a lot on plugs, no advantage and some of them actually have caused problems (electrodes burning off, reach into the cylinder is too much and smashes into the top of the piston)

 

i been real happy with my demon coil and wires going on 4 yrs now.it did improve responce and smoothness originally, but i was all stock back then. i think the tune would have taken care of that. hey jim, did you know the oem autolites had 3 each of 2 different numbers? something to do with the wasted spark system. iv e been running same number plug sets myself. i havent noticed much if any difference between motorcrafts, autolites, bosch fusions or the ngk`s i`m running right now.
