There is much debate on todays intakes but the ones that lead the pack are AEM and DC Sports. In my Honda I installed an AEM Cold Air Intake and I have no compliants. I seen most of my power gain in the 4500 rpm range and a little help on my bottom end. However, remember that the cold air intakes filter sits close to the bottom of the car so you might possibly want to purchase a bypass valve to try and avoid and water getting into your engine. Hope this helps.
