im thinking about getting a CAI, but the question is which one? i've done some searches on the forum, but no real clear answer exists, so i figured i'd just ask. So can anyone tell me which one is better in terms of cost, performance, installation, and looks. AEM claims to outperform TRD from what i've read, seems to be a bit more expensive, and comes in a few different colours. Not too sure about installation, can anyone give me a clear answer? thanks
