K&N AirCharger 2.7 Ecoboost
Installed Aircharger over a year ago and I do have to say this really is a great bang for your buck. I've had zero issues with it. Truck feels a like a rocket under boost and you can just hear the air screaming into it as well. Way better than the stock airbox and filter has even remained very clean after a full year of dust, salt, and mud.

Looks good!
I bought this for my 2005 xlt. The fit is good and all the parts are good quality. I was missing some hardware in the box but still got the job done.

Easy DIY fix
The dealership wanted a lot to replace this filter and the cabin filter. I decided to do it myself. The air filter was easy. The cabin filter was also easy once I watched a YouTube video. Both filter seemed to be upgrades from the factory.

It can breath
Product was good, pictures are deceiving. They have changed the design of the breather so one of the vent tubes is located by the mass air flow censor instead of both up by the throttle body. I think the old design looked better but nobody has updated their photos. Called k+n directly for this info. Does not affect performance

Not sure what i was expecting
But I bought it at my local advanced auto cause I didn't want to wait..took maybe an hour to hook up which I'm still not sure if it's seated right(not sure where that stupid rubber grommet sits)but whatever..this along with my awe exhaust makes it sound wicked! I'm in love..pretty sure I went through half a tank of gas in half hour from just hitting the throttle to listen to it lol

Works well but dry filters are better
Works well and I haven’t had any issues but it’s an oiled filter. I ordered a dry one from another brand. Makes cleaning much easier and cheaper. Those oil kits are like $20 and the process is just more tedious than necessary.
