Airaid 400-740 Jr With SynthaFlow Filter

I installed this kit on my 2004 F-150 5.4 liter about one month ago and am completely satisfied with the results. Not only does the Airaid intake look like the factory setup SHOULD have looked, (the OE was a cumbersome looking contraption with huge silencing chambers that practically hid the engine), but the acceleration boost is quite noticeable while producing a nice deep sound very reminicient of a Quadrajet carb, (for those of us who still remember those). Some minor trimming of the plastic radiator shroud at the point where the mouth of the intake fits underneath it will yield a more factory-installed appearance, but is not absolutely necessary. I would recommend this kit to anyone wanting a nice upgrade over OE without spending a lot of cash.

ive had this product on my truck for about a month and it seems to be doin pretty good might need a little help coolin the air but at least more is gettin in. not too sure how much its givin me but along with an airaid throttle body spacer and a superchip module it makes a nice little combo. thanks alot

Received this product about 2 months ago. Love the way it sounds when you tromp on the gas, not too loud like others, and has a noticeable HP gain around 3K RPM's. I would recommend this product to anyone. Thanks AirAid!!

Got this system a couple of months ago when it was on sale and love it. Works great together and gives you that W.O.T. sound without being too loud. Throttle response is slightly improved and you can feel a little boost in power in the mid-range pulling to redline.
