Sorry this is a teaser, but I just got my 2.0T Coil Pack Conversion kit from ECS Tuning. I hope to have it installed in the next week. I know some people say this is overkill or unneeded, unless you are having issues with your coils. Well last week my cylinder 6 coil died, again. I've lost count how many times I've had issues with coils on this cylinder. I willing to see if this helps at all. I know expensive test, but it's worth a try. Well keep you all updated once installed and tested.
Also got some other parts to install:
I'm pretty sure the S4 will be running very smooth after all of this is installed.
