NGK Coils and Copper Spark Plugs

So I have stumbled across NGK coil packs for the n54. They are very reasonably priced (under $30) and with how well NGK plugs and O2s work I figured there might be some interest in their coil packs...

Coil packs:
NGK u5055 or 48206 $~30

On to spark plugs...
It has been brought up multiple times with some of my big hp buddies and their tuners on what spark plugs are ideal to run. Time and time again they have said; copper plugs with stock heat range, maybe 1 heat range colder with high hp and E85 or nitrous. After searching for a while, digging through cross reference sheets and plug specs, I found a couple new options

Spark plugs: Stock heat range has avoided me still.. haven't come across any

Champion REA8MX / 991
1 step colder than stock

Champion REA6MC
2 steps colder than stock

NGK LZKAR7B / 5942
1 step colder than stock

NGK has about different 8 plugs that work with our cars, ranging from $6-18, in that case I'd go with the 95770 as it's tried and true. but with people starting to use the m4 plugs and other thing I figured I'd throw this up... I plan on grabbing the NGK coils as I have a 2008 and all my coils are original and not a single one has gone bad somehow, knock on wood.

I'm also gonna try the Champion plugs out. I got the Autolite 5682s to try them and they did not work at all. Misfires all over

These are just cheap alternatives, none have been tested yet, my buddy ran $2 cheapies in his 1100hp STI without issue. Even if the plugs turn out to be a flop, I think the coils should be alright.. if anyone has any experience with any of these let us know

Which champion plugs are you going to try, 1 or 2 steps colder?

Champion plugs are garbage. At least every time I've used them on a vehicle they've been complete sh*t. The NGK coils I'd be interested in trying though. Also, I had the same experience with the Autolites on my ST setup.

Yea I've recently gone ST and I've heard the champions aren't too great.. there are a few NGK standards that cross reference to the champion plugs tho if that brought any interest..

I am running the 95770 right now

Those NGK coils look a lot like Bosch ones. I still think NGK 95770 are the best plugs and I have tried almost everything out there. My second favorite would be M4 plugs

They look like the Bosch coils, but I'm sure NGK made a better design on them.

I just wanted to revisit this as I got both the coils and copper plugs in.
The coils, I like quite a lot. The electrical connectors on top are a lot nicer then those of the Bosch, and they also sit on the plugs better IMO, my idle after warm up doesn't seem as bouncy/choppy as it was before.
The plugs, at .020 gap on my 5862 running 23psi, misfired. This is the normal gap I run on my car without issue with the 5992's. I may revisit different gaps on these plugs in the future for testing.

The NGK 5942's. I won't try the champion plugs as they are garbage to me, and have been any time I've ever ran them on a vehicle.

The autolite 5682's misfired all over when I tried them, they felt cheap just gapping them.

Yea you can gap them with a finger lol... My 5862 were in the car for 1 hour before they came back out...
Thats all it takes, drive 5 miles to my open logging/pull spot. If they don't run how they should, back out.
