I made good experiences on spark plugs with 4 mass electrodes in non aspirated engines. Smoother idling, quicker throttle response.
Bosch is recommending this 4514 only for the n/a 2.4 engine, but you can use almost every spark plug for both engines, and gapping should not be a problem with these plugs 
Any volunteers?

No volunteer here. Since the PT turbo and Neon SRT-4 came out we have been told to stay away from platinum plugs in a turbo engine. The turbo engine runs hotter than a non aspirated one and platinum plugs have been known to melt. There's a good reason Bosch doesn't recommend platinum plugs for turbo engines. I do use Bosch platinum plugs in my wife's '04 non turbo PT and they work great. Besides, I've been using the stock Copper Plus plugs in both my modified '03 GT and my highly modified '05 Neon SRT-4 with great results.
