I had a AEM Brute force air intake for my 06 wrangler I noticed when the engine was started and while accelerating, the intake made a annoying as hell whiring noise. So I got a banks ram air intake. The diameter was larger than the aem. The parts including the filter seemed better than the aem. But once installed the banks was alot quieter and makes the engine sound a little deeper. I will see if my mpgs get better but go with the banks if your in the market for a intake.
