Use Delphi coils - avoid Bosch coils
Both Delphi and Bosch are OEM suppliers of coils. The Delphi coils are about 50% more expensive than the Bosch. Last year, my independent garage replaced my coils with Bosch coils and I had constant misfires. I switched back in the fall to Delphi and the car runs great. I am FBO with upgraded turbo, tune, etc. so your mileage may vary, but I suggest paying a little extra for the Delphi plugs as it is well worth it.
