For our cars I would definetely stick with Delco judging by the results people are having, including myself. Bosch is just meant for a different level of perforamcne and engine, not for kids "hot-rodding" a 3800 V6.
Bosch is intended more for high performance / higher revving engines such as BMW, Porsche, Mercedes, Etc. which is why they all come with Bosch plugs and wires stock, and is also as I mentioned before, the reason many NASCAR race teams, and 99% of Indy and Formula 1 race teams depend on them every week to win race after race. Why? Because they are NOT racing little 3800'* around the track, they are racing high-performance 600HP motors from GM, Ford, Chrysler, Mercedes, Audi, BMW, Ferrari, Etc..
Now go put AC-Delco plugs and wires in your brand new BMW, Mercedes, Porsche, Audi. or even Formula 1 race car and watch how far you get. lol.
Once again, I'm not trying to start a fight here, but sometimes you gotta look at both sides of the fence.
