How much HP will an AEM cold air intake add to a 03 Eclipse GTS V6?

AEM should provide HP curves for their units. The only way to determine the possible HP is by testing. I'll bet the HP increase is not much and only for a narrow rpm range at WOT. They may only give you peak HP at ideal test bed conditions, but that will be at a certain set RPM value that looks good to the marketing department. The only way for you to tell HP on your own vehicle is to do a before and after dyno test at various rpm's and throttle openings. If your doing 1/4 mile tests you'll need to do a bunch before and after installation to establish an average value.
