Ok, so I figured I'd post some findings and what I think might be the root cause of the various cracking the 06H version CPs have had.
I know there are various test cases where cracking has been an issue but to me this makes sense in terms of root cause. I could be way off but figured I'd contribute something here...
- I got my 06H CPs and ran them for about 500+ miles without the adapters. After that I checked them and there were no cracks in the jacket.
I think this is because without the adapters the CPs are perfectly centered on the spark plug terminal; therefore no lateral stress is exerted where the CP meets the spark plug terminal.
- When I installed the adapters with the CPs I made sure the seal around the neck was pushed through the adapter to ensure the bottom seated on the terminal of the spark plug.
When putting the adapter and CP in see how the bolt hole and adapter hole line up

I think this is the root cause of why they eventually crack. It's a small amount but the pressure exerted to align the bold hole is IMO enough to exert uneven pressure between where the CP meets up with the spark plug terminal and over time (heat/cold/heat/cold) eventually causes cracking.
My proposed solutionI think this has been proposed in an earlier post but I thought I'd share some pics of the method and the after results.
I have yet to buy a new set of CPs to test this theory but again it's what made sense to me at the time.
Pull the rubber off the neck of the CP to allow the adapter go through without any resistance. You'll also not there is some play between the adapter and the neck of the CP. This is good IMO.

Now put the rubber boot on the underside of the adapter. This will eventually seal to the valve cover like the old CPs would. There should be enough play at this point to let the CP to center itself without exerting any lateral pressure on the connection between the CP and spark plug terminal...

Note how centered the adapter and valve cover bolt holes are aligned.

In short I think this also persists with the metal CPs but it's not noticed because of the plastic jacket.
What we could do is open the bore of the adapter.
I still recommend the steel coil packs....if they worked for the MKV they will work for you.
V1.3's and V1.2's are back in stock. Tomorrow they will be packages and all back orders shipped.
I agree the bore diameter might help. Even through I have three out the four cracked I don't have mis-fires so I'm good. None the less I've been really happy with this upgrade.
You got all up in that, nice work man. Very impressed. [wrench]Quote:

id like to pull mine to check for cracking. i have NO misfires. I wonder if the vw dealer would warranty these? I have a buddy that works there that i already get a discount on shit, so they dont have to know i dont have an mk6
Go for it. Local buddy did the same thing and got them replaced....Quote:

3.29 AM....no one up?
Everyone , please only buy MKV Coils. Forget using the MKVI units.
RED MKV FSI Coil Packs - 06E 905 115
BLACK MKV FSI Coil Packs - 07K 905 715 F
BLACK MKV TSI Coil Packs - 06F 905 115 F
These correct for those who may not know.
CorrectQuote:

looking at my receipt, i definitely bought the 06H905115's
Looks like the only issues have been with the 06H. I have a crack about a inch on one and have had some misfires every now and then during startups. Will replace with old CP's and see if still happens though. If you dont have any cracks Nate i would try Vic's set up so you can avoid any.
The MKV FSI ones are metal units . Same goes for the MKV/MKVI Rabbit ones.Quote:

TSI is 06H
06H is the engine code starting # for the timing chain TSI Motor.
06F is the engine code starting for MKV GTI FSI
07K is the engine code starting for MKV 2.5 Rabbit
06E is the engine code starting for B7 Audi A4 2.0 FSI
i.e. all TSI engine part #'s will go 06H XXX XXX
I took apart a TSI Coil pack today (06H XXX XXX) and I believe the boot is somewhat off centered. I dont know if the locking tab pushes it to one side but doing what you did centered it back.Quote:

This is good information Issam... I honestly think I'm just going go with the ones that we know work and avoid the 06H's all together.Quote:

I wonder if that is where the stressing them out occurs that leads to a crack in the outer shell. I am going to continue running them since they seem fine.
that's what I did.Quote:

so i pulled all of mine last night and have no cracks...Quote:

The 115D seals, fit the spark plug well better while providing a block from water and dirt into the wells.Quote:

Another difference is the resistance in Ohms, measured between the sparkplug connector, and the harness connector pin #4, the 115D coilpacks measure ~2.3 megOhms, the Bosch 06H CPs measure Infinity Ohms between all of the harness connector pins and the sparkplug connector, the output of the secondary winding.Quote:

Audi B7 A4 Quattro 2.0T Coils, Part# 07K998715F $80 (ECS)
Coil Pack Wiring Harness Replacement Part# 1J0971658L $50 (ECS)
Bosch Type EV6 Injector Connector Kit (USCAR connector) $17
Automotive High Temp wiring $10
It will be a weekend project since I plan on removing the old ICM/Coilpack, Injector, and secondary O2 wiring. Does this look like it should work correctly? It looks like everyone is leaning towards 07Kxxx715F coilpacks as these do not have the plastic insulators that has been shown to cracking.
Issam - Can you please provide me with some cliff notes? ..so I can convince myself to purchase these already.
People are having trouble with the coil packs cracking?
Which coil packs are working best with these adapters?
Any tricks people are figuring out now that they have been out for a while?
And what benefits have people been seeing from these?
Thanks a million! Really appreciate it.
you seriously can answer all of your questions on teh first page of this thread.
But not really...... Thanks though.Quote:

I just converted my AEB style coil packs to the push down type, so I'm probably not going to be in the market for the FSI ones for a little bit yet. However I'd like to know if there's enough of a gain to make it worth my while to do the switch when the time comes to replace my pushdowns.
06E/07K/06F coil packs are what are working. The first post has some of the questions answered as to the benefits.Quote:
