The AEM cold air made a pretty significant difference once it was installed. It sounds awesome, especially with the exhaust system thats on the truck with it. The truck sounds much more throaty when you get on the gas. It looks much better than the stock air cleaner. It made a huge difference in the low to mid range of power. noticeable from the second you put it on. Would recommend to anyone. Couple parts hard to put on but well worth the trouble.
