I understand that the Audi coils are a 4 wire coil. Power, Ground, Signal, and Ground to ECU. Where as Honda is only 3 wire Power, Ground, and Signal.
Would the Audi coils be better from a noise standpoint? Any fitment issues on the lower valve cover?
Why reinvent the wheel?
We tried over 20 different COP units -- German, US, Japanese -- to find ones that work exceptionally well on the 911 engines.
* checking for fitment on the engine:
* whether it would clear the frame rails with the engine in the car so you could actually service it (we once got a customer's car in that another shop had done -- impossible to R&I the coils with the engine in! Idiots.)
* whether they had the firepower to support serious cylinder pressure -- so far, we've done over 125hp/cylinder without a problem. A drag car on the dyno did 44psi, no spark issues.
We settled on a Toyota/Lexus-application COP that is easily supporting 125+hp/cylinder. We were blown away when we saw a 4-cylinder Time Attack car on the dyno run 45psi boost with these COPs and have no ignition issues.
They fit quite securely, or you can restrain with the old RSR-style hold-down tabs if desired.

If so how much?
Yes, have done that before.
Which sensor do you have -- or do you need one, too?
Last job we did with machining + sensor + connector was $245.
