I was going to ask about the benefits. Here is my answer.
I'm going to do this next check.
Thanks again for the info and write up.

These are some benefits of this setup:
- Expect just about every aspect of the car to feel better.
- Improved throttle response (especially between shifts), little to no cruise partial throttle jerk.
- Stable and smoother idle.
- Acceleration is noticeably smoother.
- Gain HP/TQ (8-20 hp is the norm, mod dependent)
- Increased gas mileage (I get 1-2 mpg better mostly highway)
- Ability to run a bit more gap. It's like driving a new car, you won't believe the difference.
- Handle 650+ HP, tested to 800whp
- Run more boost
- Greatly reduce or eliminate partial throttle cruise bucking.

good write up,
but i dont see the point in it. yes you are running COP, but its still wasted spark (firing 2+3 at the same time and 1+4) and because its still wasted spark it wont make any difference to anything logically. You are still firing 2 coils at any time. Potentially this could be worse actually because the honda coils are made to fire 1 time every 2 turns of the crank, but now theyre each firing at DOUBLE their standard rate (due to wasted spark). Also, the ECU is controlling coil dwell right? How do you know these coils suit the dwell that the stock coils run?
Never understood how COP can make evos "run better" or "make more power" etc. Unless the stock coils are pathetic.
I dont see the point in it unless you run an aftermarket ECU and run proper sequential ignition and adjust coil dwell correctly so you dont burn out the coils in 10k kms.....

you didnt get everything i said did you?
They will run double the number of spark discharges, but also you dont know if the dwell time is too high or too low. Too high and you get premature wear and too low and you get a crap spark. Why change when you technically get the worst of all worlds? Either go standalone or nothing IMO. These reviews of COP being a whole world better and giving 20horses just sounds retarded to me. Maybe i should try it so i can see the light...............

I ran one and back to back with the original coil packs and it made a massive improvement. Also i removed the OE earth line from the wiring harness and made one to earth on the engine black, so it was much shorter and larger 
Don't know if it helps, but in the end the OE coil packs earths next to the thermostat housing, almost a metre of wire :s
