Sparky83 I have to ask how you came up
with the milage numbers. Hand or truck computer?
Sean
tank to tank comparison... gallons used to miles... first got the truck i was seeing 14-16 mpg.. that was with the mud packed air filter... (po must have loved mudding).. changed the intake since i wanted a CAI and was easier to work on.. i saw a 3mpg rise afterwards (averaging 17-19mpg)... but like i said in the previous post... i was tributing that to the fact that the stock filter was plugged up.. best mpg ive had off my trucks 22.. but that was going down hill and a stiff wind on the back of the truck...
I just removed a KNN filter from an older chev gas and put on a stock filter, the KNN was tightened to much and collapsed the intake giving it a unfiltered leak. I used a heat gun to repair the intake.
The stock filter is twice the size of the KNN.
Why people would install an intake that allows a lot more dust thru, and is noisy, is a way above my pay grade. But as a mechanic I love to see people destroy their engine, it is great for business.
As far as getting 3 MPG. increase that would mean you would have to get about 50 HP addition to get that kind of increase.
Just a thought!

Yea, they claim anywhere from 3mpg to 20 +- more hp, I think they are talking about dollars in their pocket and destruction of your engine.
Not to mention the extra noise and lower resale value. If I saw one of those it might be a deal killer.

higher HP does not = fuel mpg... if that were the case every 600 hp vehicle out there would be getting the best mpg over the vehicles with far less.. what the aftermarket systems do is allow more air into the systems to allow the fuel to fully combust.. burning more efficiently = less waste of fuel needed to output the same effort.. the less your engine has to work to breath the more efficiently it can run.
as for K&N allowing more dust.. i have K&N filter on my stang and havent seen any dust/dirt winding up behind the filter.. now when i had the stock filter on it i did just about every time i pulled the housing apart... the only reason you would get more dirt behind it is from not inspecting the filters for defects OR as you stated on that vehicle you pulled one off of where someone improperly installed it by over tightening the heck outta them and allowing air gaps in the plumbing..
When I bought my 2000 F250 the air filter was dirty and the box was not in the best shape. I did a lot of research and ended up purchasing the FA1759 Ford intake system from Rock Auto for $171.
Does it make a difference over stock, I have no idea. I know it certainly helps with my situation and I was perfectly happy with spending a bit extra in order to make my truck run better.

When I said it would have to produce extra HP what I ment it would have to give you free HP with no additional fuel. I dyno'd a lot of motors. with and without an air filter, with and without an exhaust system, It does not increase HP.
If you want to know about the air inlet system ask about what the warranty covers if it passes dirt

$.02..... I bought a JEEP Wrangler, used, with like 5000 miles on it. It had a K&N system on it. I didn't like it so bought all the parts and returned it to stock.
I bought a 2011 F250 w/ 6.2l gasser with about 10000 miles on it. It had an Airaid system on it. It was obnoxious loud in the cabin when I hooked to my 5er and started pulling. I bought all the parts and returned it to stock.
Funny thing.... on BOTH vehicles, my fuel mileage actually improved with the stock system; not by much, about 1/2 to 1 mpg. (hand calculated)
But, that is just me, with my vehicles. Can't tell anything about someone else's rig and experience.
Ford has paid engineers to perfect the filtering system on a dyno that will extract the most HP and MPG, and do you really think they screwed it up?
People buy aftermarket systems mainly because of the lies the sellers tell (hype) and they figure; "it's easy to do and they said it works plus it makes more noise so it must be doing something". It's doing something alright; letting unfiltered air in which can harm your engine over time and do you think the sellers care about that? No! There have been many tests proving the aftermarket systems are worthless and even if they did extract 1 extra hp at 5000 rpm's it would be at the expense of your engines' reliability and longevity.

Are you referring to my reply to your comment about the AIS?
If so you would be the first person I've ever heard say the AIS is sub par.
I just can't agree with any of this in regards to the AIS.
On one hand, Ford engineers where the geniuses to put a snorkel on the intake of my Focus that has no purpose but to apparently make the car idle rough. That was gone 14k miles ago. On the other, International put a restriction gauge between the turbo and air filter, and if it never moves then the air filter must not be a restriction. because the turbo still isn't pulling it's max amount of air.
On a 6.0 it's lighting $20s on fire to put in a CAI, especially if you watch IAT1 and your "cold" air intake causes intake temps to increase. On a 7.3, eh the stock filter was marginal but probably fine for stock power levels of 210HP when the PS came out, maybe not at 275HP. On a Triton, using an oiled K&N would more likely junk up your MAF than actually gain you anything.
