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

[Zecca93]

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:

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

The reason I started this crusade was that I was seeing people spend a lot of money on aftermarket filters based on the word of a salesperson or based on the misleading, incomplete or outright deceiving information printed on boxes and in sales literature.
