Air intake 2011 SD V8 6.2l K&n or Air aid

K&N 77-2582KTK - Intake Kits, Performance Intake kit

AIRAID Intake System For 2011 6.2L Ford Superduty F-250 / F-350 - SVTPerformance

Im looking for an air intake that will add horse power and will give more of a rumble when you lay down the pedal. Ive been thinking about getting the air aid but then i just came across this K&n one. Please let me know what you think.

also will either one increase mpg?

Increase mpg, not in my experience as I didn't notice a difference. A custom tune helps to correct the MAF and help get the full potential of the intake.

I have the K&N Intake on my 04 6.8l V10. I currently have the exact Airaid intake in your link that I am doing work on for a customer. The Airaid kit is very nice with a nice big filter and a nice thick intake tube, nicer than my K&N IMO. I would go with the Airaid. You will notice more intake noise with either kit.

I think by now that Ford (and other manufacturers) would put quite a bit of effort into designing air intake systems that achieve maximum fuel economy while providing adequate engine protection as well.

I doubt that any after market intake system will increase your fuel efficiency no matter what they claim.

Noise is a different story though...if you want to hear the engine a bit more than any of those choices should do the trick. They look pretty equal to me, they both have the potential to ruin a MAF sensor...does the 6.2 have one of those near the filter element?

The MAF is very close to the air filter. It could cause problems with oiled filters if oil is applied to liberally.

The only improvement a CAI will give you is more noise (which seems to be what you are looking for). To get any real HP improvement from a CAI, which will still be very little, is with a custom tune. The factory intake already provides sufficient flow for optimum combustion. Only if you start moving into the region of forced induction is a CAI required, as the factory intake will then restrict the necessary flow.

If you are to go with a CAI, be careful with your filter element choice. Many of the filter companies, namely K&N, promote their free flowing design...but there is a great sacrifice in "fine partical" filtration. I don't find it to be a good trade off to have slightly less flow restriction, in the risk of engine damage. Am I saying you will experience engine damage with K&N, no, but it doesn't stack the odds in your favor. I ran my 01' SD 5.4 with a K&N CAI with no problem until I sold it at 85k, but for my 11' I did my homework this time.

I ended up swapping out my filter element with a AEM Dryflow filter, as I was looking to get filtration greater than the factory filter....while still getting slightly less restriction. I also perform the modification posted on this forum by 5StarTuning:
http://www.ford-trucks.com/forums/10...er-duty-2.html

Good luck in whatever you decide. Just remember you won't really see much difference with a CAI other than noise under the hood, and be careful of your filter element selection. Also, try to find a CAI that truly is a CAI and not a SRAM intake....pulling in HOT under-the-hood air is not a true CAI. The fully enclosed system 5StarTuning is looking into is your best bet.

I agree with RAPR...and here is the proof..........
Recently, Testand Corporation conducted an ISO standards test on automotive air filters which can be viewed at this link: http://www.dieselbombers.com/chevrol...r-testing.html. All I can say is this explains in detail the reason for

You must be a paid spammer to make a statement like that...........in addition to the oems, Ford racing publications & ISO 3rd party tests, it is just impossible to make a statement like that without laughing......the TBS units came out in the late 80s for EFI....they were proven (even by the mags at the time such as Hot Rod, etc) to be absoultely phoney in their claims fir EFI applications....demonstrated on chassis, engine dynos & at tracks!

I had a K&N in my 2000 V10, and we used them in all our desert cars as well. My dad got paranoid when I showed him in the intake tube and how it was lined with dust. I love the ease of cleaning the filter and never had any oiling issues in the 10 years I had it, but dust does get past the unit.

I have a complete AFE intake on my '11 250. I went with the dry filter setup since the MAF sensor is right behind the filter. The only real noticeable difference is sound when the pedal is smashed. Other than that, its nice and mostly quite on the highway. As for MPG increase, I haven't seen any change. I still get 11-12 around town, and 14 on the freeway.

So, other then spending money what was gained?

I also had K&N in my 93 F-150 4x4 and dust always got in. Many miles later I learned it polished the cylinders so well that it no longer had any git up -n-go....

The only after market filter I've used since is a Donaldson filter. Ford's AIS filter kit using Nano-technology that my Blackstone Lab results confirm. It did not get me better MPG's nor turn my gray hair black and reduce my belly fat but knowing the turbo in my old 7.3 is healthy is good enough for me!....lol....If Ford had the Donaldson filter as an after market for the 6.2 like they did for the 7.3 that would be the one to run.


It's the same technology they use for the M-1 Abrams tank and when it comes to air they do suck!....

Well, I am still waiting to put the tuner on I got from Mike at 5Star. I also live in, well my truck is in northern CA right now with the parents, because I'm still in Afghanistan. Once I do put the tuner on, and get everything settled, I hope to see an increase in mileage and overall power output. Northern CA isn't a dusty environment like some other places. So I don't really have to worry about polishing my cylinder walls.

I got the K&N full system for my truck- got it as a gift from the wifey. Kinda hard to kick it back. Anyway, I solved the lack of filtration problem by putting an AEM dry filter in place of the K&N. I have put AEMs on the last 2 vehicles I have had, and it flows better and traps fine particles well.

As far as the seat of the pants dyno and manufacturers claims, I don't hang my hat on the "an intake give you X amount of horsepower" thing, either.

Without a tune (which I will eventually get), the intake does not do much, if anything. End result? More pleasant when you hammer the pedal down, and nicely compliments my exhaust. That's worth something to me

I did a muffler delete. Kept the ffactory piping and resonators, just simply eliminated the muffler. Good sound without being too loud. Sings nicely when you put your toe in it!
