All, I have for sale an AEM Cold Air Intake (P/N: 21-8405). It was on my 2008 truck for a while, but now I'm going in a different direction with my engines intake and thus, I removed it.
(sorry i dont know how to rotate the picture. looks good on my photobucket)
Nothing really wrong with it. There are some cosmetic scrapes on the tubing, and some smudges on the intake but over all it performed well, and I LOVED the throaty sound I got out of it.
I should have all the parts that you need to install it (takes all of 1.5 hrs if that). The only thing you DO need is a little hose you will see in the picture (the 5/32" hose). I forgot to take that off of my truck, but there is a sample piece in the box that you can use to take to any auto-parts store, and they will chop a piece off for you ( I got a 2 foot length for like $3 and used a little more than half of that). The hose is used for the fuel pressure regulator in the back of the engine and connects to your stock intake. Other than that, you will have all the directions that came with it from factory for an easy install.
Last but not least, I've seen them sell for $383 ill ask $200 for it.
