Very clean kit.  Used for about 3 yrs.  I have all instruction manuals and data performance sheets.  Per K&N about 13hp and 13lb ft of torque to the wheels.  Very good gains from just a cold air kit.  It is missing the rubber grommets that go to the bottom of the bracket that can be found very easily at auto parts store very cheap (maybe a couple of dollars) or through K&N's own website I'm sure. Their only purpose is to have the bracket bolts to have something to grab to. They do not affect functionality of the product! I guarantee you when you install you'll see what happens m talking about. The go on Nader the two drilled holes on large bracket you can see in picture. I have the screws just forgot to take the grommets off of truck.  You may can use the ones on the existing filter box you have now. You can actually use the provided bolts and buy a cheap nut and washer to secure the bracket down even though there is the included upper brace that mounts towards the grill and secures it fine. I personally don't think they are even needed but your call.  I have seen people not even use the large bracket at all and just run the tubing straight to the intake with no issues. I recently cleaned and re-oiled the filter about 6 months ago so it is good to go for another couple of years depending on your driving characteristics.  As shown I have the original box as well and the original stickers that came with the kit.  You can feel a noticeable difference in power especially in the mid rpm range and Smoother idle in my case as well.  Honestly not a whole lot of fuel economy difference in my case.  Maybe saved .5 miles to the gallon.  These sale brand new for almost $300.  May fit other years. I feel this is a very good price. I sold the truck so I no longer need it.  Thanks for looking and please check my feedback and bid with confidence!   I ship in U.S. only!!  Sorry
