K&N 57 Series FIPK Air Intake (50-State Legal) - 57-1531

Very fast shipping, installation was easy bolts right in where your restricting stock air box is, price was high in my opinion, but overall i am pleased of the purchase.

The heat and water shield, along with the plastic intake tube make this the perfect cold air intake. The plastic does not transfer heat to the intake air like the metal ones do. Be careful when installing. Two reasons. First, the hose clamp will easily fold the plastic intake tube if you tighten it too much. Second, it was impossible for me to fit the intake tube into the rubber-like transition collar with the collar clamped in place on the intake manifold. I had to remove the collar and work hard to get the plastic tube into it and clamp it, then install the whole thing onto the intake manifold. I haven't had it long enough to figure a change in fuel efficiency.

Very easy and quick to install. Noticed increase in performance immediately. Love the sound from the turbo!
