Installed mine today. I'm a total noob when it comes to a lot of this, so it took me about 30 minutes because I wanted to make sure I did it 100% the first time.
Honestly though, all you need is a flat head, a ratchet set and maybe pliers.
The good: It looks great, is easy to install, and at $180USD +Tax/Shipping it's a bargain compared to other intakes. It sounds awesome/ Honestly reminds me of my buddies WRX which I wasn't aiming for, but I'll gladly take. (No, it does NOT sound like a WRX, just similar, hard to explain.)
The bad: I've got one word for you. Drone. On flat, you really don't get it. On hills however, especially anything remotely steep, you're gonna have a drone. Now, it's not necessarily a bad thing, but I could see it being a big put-off for some people. On the plus side, the drone at least sounds good and you feel like you're in a race car.
Very satisfied, and can't wait for my next mod now, the big one, wheels. =D
