Think theres a difference in brands?
I bought a EBAY Intake System for $17, After that My car had a crappy idle and sometimes stalled (due to leak in hoseline from intake system). Now I said screw it, And wen't out and bought a AEM Short Ram Induction System for $89 and everything seemed like it fit perfectly as if it was mean't specificly for my car. I also noticed when hooking the tube up to the area of where it connects to the throttle body it fit perfectly, instead of that crappy rubber sleave that was wider on one end to fit over the throttle body. anyways the whole point of this post was to tell you peoples out there that AEM is worth the $$$.
