16V/B234 coil pack options?

They fit very tight as they are.
I used DEI shielding, it's horrible and I would actively recommend against using it. It is off the car now. They advertise it and market it as a suitable wrap for exhaust manifolds and it plainly is not. It is embossed aluminum backed with basalt wool, which sounds great. The glue they used to attach them together is flammable and catches fire and burns and stinks. I emailed them about it and all they said is that some smoking is normal.

That’s disappointing. I was thinking of something without basalt wool; conformed embossed shielding that’s bolted down to threaded standoffs welded to the manifold flanges. That should keep enough of an air gap to serve as insulation. Either that or sandwich rock fibers between two layers of shielding. I’m just paranoid about the amount of heat that my next exhaust manifold is going to radiate into the engine bay. The way that VAG does it for V10 headers is pretty nice.

As for the coils, they do kind of stay in place but wouldn’t want to keep them unsupported. Will look into designing something soonish.

If anyone was wondering, I ended up using the long VAG coils. Swapped to a spark plug that uses the smaller hex that the coil shield locks onto and they sit pretty secure. I probably have 20-25k miles on that setup. I used the original plug wire cover to hold them just a bit more.

I’ve also tried a set of VAG short coils, as most information points to but the connectors end up directly interfering with the cast thread stands for the wire cover.

I love seeing replies to this thread, thank you all!

Let me know what part numbers you ended up using for the coil packs. I have the 16mm hex plugs as well; they are just easier to install in my experience.

My LS2 coils work but they are unsightly and kind of a pain to deal with whenever the valve cover needs to come off.

Can do. Going to pick the car up in an hour or so and can grab them for you when I do! It’s been rotary time for the past week, time to swap out.

There are places that sell embossed stainless sheet, it's just harder to come by. That's what I would prefer in the future. Wrap the manifold in ceramic wool and then spot weld the stainless shielding around it.
