There seems to be a lot of different methods of working on the coil pack problem so I'm going to take a stab at making a definitive reference. Please chime in if I post any misinformation, partial information (chime in with further info), or additional products or links that may be useful.

Note: I will be editing and adding extensively to this post as I get all my information together.

Wrap your wiring in this and it will dodge most of the heat.
Wrap your wiring in this and also buy the rubber boots for your coil pack connectors and I think you'd be pretty golden.

* Conversion to mk5/mk6 pushdown style
The use of the mk5 or mk6 pushdown coil is a new trend in the 1.8t tuning community which has shown to create a stronger spark and has allowed the use of a larger spark plug gap. This larger gap allows for a better burn and thus improved fuel economy, improved engine idle, and the ability to use more aggressive timing which will result in more power.

The mk5/6 coils will push straight into any 1.8t valve cover as is, but they will stick out the top significantly. This installation makes long term reliability questionable at best. To meet this demand a few aftermarket shops have created billet adapters to adapt the various 1.8t valve covers to fit these coils.

Long term reliability of mk5/mk6 coils in a 1.8t platform is not yet known, but as of this writing these coil packs have usurped the famed 'Hitachi Bolt Downs' as the coil to get for the 1.8t platform.

On a side note, mk5/6 coils are less expensive than Hitachi Bolt Down Coils. The caveat to this is that adapter plates are really required to make a proper seal and fit.

Mk5/6 coil packs are compatible with all 1.8t motors that utilize a 4 pin coil pack harness. The 3 pin harness in early 1.8t motors is not compatible with the mk5/6 coil packs.

Nice post groggory :thumbup:

This will simplify a lot of the confusion about the differences between replacement options. I'm also thinking now that i should get a shield to dress up the bay.

good post. I still don't understand the idea of putting a metal shield over your valve cover. You would think that would keep the heat in and cause the wires to crack sooner. They do look nice though.

I think the metal shield would protect against direct radiated heat from the exhaust manifold/ turbo..which is the biggest killer.

I think of it this way...If I put meat in the broiler, what happens when I cover it with aluminum foil and what happens when I leave it open? Open = crispy delicious outside (dead coil wires). Closed = Very hot meat but soft and juicy. But even with that said, I think the OEM style heat shield is still the right way to go. I have no data to back this up. We need to get someone in there with a thermocouple and take readings at a few different spots over various driving conditions.

I think one is for 2 pin (injectors) and the other is 4 pin (coilpack.)
That's rad! I want to buy a set!

How hard is it to de-pin the injectors so I can get the wires through that little hole? This would look super nice!

Are you guys who've replaced the whole wiring harness noticing cracks all the way back to the ecu? Based on the level of PITA associated with changing the whole thing I think I may just take the INA route.
