Default screamin demon coil

not a chance. only thing it lets you do is gap the plugs a little farther. might see one or two extra ponies, it will not cut down ETs by a half second.

i had one just as a stock replacement, spark is not going to help with any power or E.Ts

I think the only benefit may be a stronger, more consistent spark through the RPMs. Definitely not the manufacturer's claims. Maybe beneficial to F/I guys. No coil-on-plug option for the 4.0's (that I know of), so maybe this is the best option.

I would say that if your stock coil is OK that you will see NO difference. No coil is going to drop your times .5 sec! or give you 2-3 mpg mpg. If it sounds to good to be true.......

I have had two so far, one on my previous 95 V6 which made a huge difference. I picked up 2 MPG and car ran like a rocket. Based on my prior experience with the screamin demon coil, I put one on my 05 V6 along with the Livewires igntion wires. The 05 also picked up some MPG's as well as the car really wants to jump to redline!

no wires just the coil, suspension setup is sold. I only got it because I found it for $50 from a forum member and I though it might help when I add the vortech
