the short ram won't lack any power, especially on our engines. just get what you like. the difference between the injen and AEM are purely looks. the difference in hp gains won't be noticeable, i'm sure. adventon.com has the polished AEM intakes for $130. the injens run about $200. so it's up to you. you make the call. besides, i'm sure not too many people on these boards went from a SRI to a CAI or vice versa since an intake is an intake. just as long as it draws air in in a less restrictive manner than stock, it's all the same to me, besides the looks, of course.
