Selling my AEM intake. Cold air intake for the Si that does not require battery relocation. I was running this on my ct-e setup for about 1 year, 10,000 miles. IAT consistently 7* above ambient while cruising.

There is some scratching on the bottom elbow from the fender liner. Includes aem dryflow filter wrap and extra coupler for zdx throttle body. All hardware and instructions included. $150 shipped
