INSTALLED: Evo IX SpoolinUp COP & Denso IKH24 plugs

[scheides]

Awesome dude! I'm glad you like it, next time you're up here, perhaps a re-tune with a bit more boost is in order I'm glad someone else had a similar experience as me, not an insane improvement but just general driveability and overall smoothness gains. One guy claimed he saw like 40whp gains with this....there's no way, unless his stock ignition was fuct up. Will be curious to see if you see any mileage improvements.

I noticed the same differences you speak of when I put together my COP setup using Intrepid 2.7L coils.

There's two ways to look at a mod like this:
-it's not needed if the car isn't breaking up, its one more thing to break/go wrong
-its worth doing if it is proven to improve driveability and power (probably assuming a re-tune to actually see it)

Either way, .030 gap at any reasonable amount of boost(24+) is fantastic! As long as its reliable, its worth doing in my book!

Jim changed his perfectly fine looking stock iridium spark plugs to a new set of stock spark plugs and gained a massive amount of power, maybe that guy had a similar thing happen or he had a bad coil/blow out.

We have dyno tested some of the replacement aftermarket expensive coils, like these http://www.lethalperformance.com/99-...0ae0dhuk8af750 and the Okadas on Hondas. Changing to a new set of spark plugs gave a measureable gain on both cars, swapping on the new coils after already changing the plugs didn't gain gain any power. We didn't spend all day playing with around with opening up the gap though either. I haven't seen running a bigger gap make a huge difference in power at WOT on turbo cars(we are normally just happy to avoid misfires though), but it does make a difference in idle, cruising and start up.

The SpoolinUp non-CDI kit is definately a nice upgrade for the Evo guys.
