I suppose it depends on year, but typically the higher performance model would want a colder plug; for NGK higher numbers are colder - thus 7 for Aeros rather than 6.
I don't have an Aero but I know my LPT uses 6 and my logic tells me then 7 for Aero.

Well my manual says 6's and that's what I've used for yearly spark plug change for 3 years now. Every time they come out a perfect light brown color and I drive my car hard so they're pretty much the perfect heat range.
I just put in some NGK BCPR7ES-11 in my aero and it runs really well. The stock platinums looked good when I took them out however the car now pulls better from low rpm and doesnt die off above 4500rpm. Also they were $17 for four not over $100.
