Not true!
Just to fill us all in on what tris wrote...
The demon coil didn't do ANYTHING that a new OEM coil wouldn't have done! All the demon coil is, is ADVERTISING for our rides.
All the GAINS that tris made after installing the demon would have been zackly the same gains if he had installed a OEM coil!!
It is tiring indeed to read all the hype about this coil and that coil. Coils all work the same, if one coil will improve the running of our engines then almost ANY coil would have caused the SAME gains!
OUR coils will run our engines up to six grand.. If more than six grand is being used then POSSIBLY a demon or other high-rev coil will improve running at those high rpm's.. But BELOW those rpm's all coils are the same.
If we read up on how coils work we will have a better understanding of WHY they can or cannot help in the daily use of our engines..

well the screeming demon coil with live wires made a major improve ment in my gas milage and mid to high torque. but i have 93 4.0 ohv. i gained 3-4 mpg city and same for highway so now im at 17 to 19 city and 18 to 21 high way depends how i drive, that extra passing power really helps when your behind sunday drivers. befor coil pack i was at 14 to 15 city and 17 to 19 highway. and idk what year you have and why you want to remove cat but its possiable to do so in mine cause my o2 sensors are before cats not after. i only have to cats but realy if you romoved one it will only help with exaust noise thats it. so over all just leave that cats and if you getting that good of mpg dont really bother with the coil pack and just to let you know you are one lucky sob to get that on a 4.0. i will be more that happy to trade you
