Offered here is a CAI I recently took out of my truck. This is the 63-series from K&N seen here for about $300. It fits 2005-2011 trucks as a bolt-in and I'm not sure on the later trucks though I've read you can relocate a part to make it fit. Up to the buyer to confirm fitment. The sound from this thing was AMAZING and my supercharger absolutely screamed. Cleaned up the engine bay quite a bit and looked great. I just can't keep the thing clean up here in CO where we have low humidity, high dust and lots of wind. Looks a little bit dirty (hence the reason for selling) but I'm including a barely used cleaning/recharge kit with this which sells for about $15 for a total of well over $300 for all of this:SOLD!. First one who posts 'I'll take it gets it' and posting questions or PMing questions isn't the same. Once a sale is pending I will post likewise and until then it's available. Thanks!
