Put your $80 in your tank and go for nice ride. If you want a little better sound get a AEM dry filter that fit in your stock air box which draws cold air from your wheel well. You can buy a bundle of bungycords for next to nothing most anywhere and put a hole by your knee and hook to your toe. This will give you at least 3mpg, if you find milage is still not to your liking and extra cords. Lol

I've never seen actual mpg gains from any after market CAI. Just a side note...using a K&N drop in filter and the larger air box snorkel tube from an '11-'14 I am getting 19-20 mpg in my '09 crew cab 6.5 bed 4x4 with a cap, assuming I'm not being heavy footed. Not bad for an older tech 5.4.

Say what you will, but I got a little over 1 mpg when I put my airraid on my raptor.

I don't know why people keep saying this. We all know it is. Nobody says otherwise. When people say CAI, they are refering to an aftermarket one.

No different than people who say exhaust, floormats, tires or wheels.

Because stock box pulls cold air from fender and aftermarket pulls hot from engine compartment.

It needs to be repeated to save people from wasting money

After I yanked the Volant airbox out of my truck, I still wanted to get more air in. The intake tube that came with the Volant was a nice unrestrictive elbow. So I left it on the truck. I know the stock box is more than adequate, but I also wanted more sound. My solution was to modify the stock airbox. I cut about 90% out of the bottom of the box. It gave me the sound I was looking for, and the stock configuration with the snorkel thru the fender well is still intact. At first I was concerned about drawing in Hot air from under the hood. Which it does, until I'm on the move. Then the intake air temp. drops to what the ambient temp. is outside, sometimes even a bit lower. Does it give me more performance? More cold air in says yes. Do I get better gas mileage? I like to think so.

I have the AEM dry filter on my 3.5L Ecoboost. With the SCT livewire, tuned or stock I get about 2to5 degree lower intake temp depending on driving conditions. MPG is say are the same just better intake tubes and a sucking sound, both of which I new would happen. So I'm happy. Once I add down pipes and exhaust I'll probably get lower mpg due to a heavy foot

Put a CAI on my old 2003 GMC Sierra 1500 z71, never saw the gains in fuel economy, even in perfect weather conditions. Have since put a K&N replacement filter in my '13 6.2, only to watch my average mpg's drop about .5. I know the replacement filter is a different setup, but I'm not sold. Maybe more power and a lot more sucking noise, but I wouldn't get one thinking it's going to put you ahead at the pump. Diesels are the only engines, even including rice burners, that I know benefit from more air.

Good grief! That is hilarious! The butt dyno....
