Review on Cold Air Intake Kit Performance Replacement Parts ... Filters by Robert Aan

I DIY for small things. Installation was straightforward, although the first disclaimer before step 1 advised getting the codes before disconnecting the battery negative terminal. The battery cable did not have to be disconnected. The hard case (aluminum tubing) feels flimsy for a $315 kit (made in China). The instructions said to install the larger of the four clamps per connection, but the clamps were all the same size. The short silicone hose connecting the inlet was difficult to attach. Use some mild soap and water to "lubricate" it. It went on smoothly. Haven't checked the mpg yet, but it definitely sounds like it's going to gulp more air when you step on it hard. In normal driving there is no difference in noise. In hindsight, I would have bought a cheaper no-name brand and saved $150 to get the same result.
