which cold air intake to get
i have a 2011 f150 3.7L V6 and dont know which CAI to get. i know there is roush,aFe,airaid,volant,K&N but what makes one better than the other? why did you choose the one you have? i know this may sound stupid but im new to cars and what does a cold air intake even do?

Stay stock - it already handily outflows the needs of a stock engine.
If you want it for looks and / or increased noise - go ahead ... BUT you WILL need to factor in an additional $400 to render it safe from an A/F perspective.
Then - there are the potential warranty issues to think aboot.
You need to search as this has already been discussed in detail - even recently.
BTW - help me out here .. you suggest you want one, but you don't know what it does? Does that not seem just a teeny-weeny bit odd to y'all?
Lastly - y'all already had a thread - what happened, ya figure? https://www.f150online.com/forums/ex...ir-intake.html

OK - fair enough.
If the OEM intake was demonstrably restrictive, then it follows that enlarging same would alleviate said restriction and potentially allow an increase in power under certain conditions.
However, Bernoulli was a very clever bastige
So - in real terms there is no benefit for a stock N/A engine, as there is no appreciable restriction, and hence no net benefit.
In fact, most open element intakes can increase the intake air charge temperatures under some conditions; not optimal. Terms used are WAI or WASHOOBI.
IF you increase the volumetric efficiency of the engine - e.g. boost ... different story.
Lastly - any MAF region geometry changes / relocation can induce uncontrolled lean conditions and must be corrected to run said 'WAI' safely - as the PCM cannot be relied upon to provide this correction - the best way is via a revised MAF transfer function specific to the WAI in question.

^^ Next to nothing. And in most cases a net detriment, as you increase IAT's over the OEM unit.

To the OP: If you send me the money you would pay for an aftermarket CAI, you will get the same performance increase as if you bought it!

There also goes yer MAF TF, hence inducing lean conditions that only proper tuning can correct.
This is also perhaps where yer mileage came from - not a ideal way to do it.
Yer Stock engine neither recognizes nor can use this extra capacity.
Idle drop - idle is controlled by the PCM so something is also amiss here as that should NOT happen.
Oh my ..... I feel sorry for ya
Nice, expensive, and Dangerous paperweight.
EDIT - please leverage the Search function - all is already explained in detail.
BTW - here's a good one (just inseret yer favourite intake name in place of Volant, lol)

Well, that tells me everything I wanted to know.
I suspect you will continue to revisit this topic until such time as you receive a response that you want to hear.
This is, in point of fact the second thread, with the same response given. What's a couple more, eh? ( ... and the definition of insanity is ...lol)
Sorry to have disappointed you. I'll stay out of it henceforth.

well i know we have two completely different engines but Im going to say this. originally I installed a spectre performance intake system on my truck, i noticed my intake was louder and i lost low end power and gas mileage with that damn open filter. I get fed up with it and ordered a true flow intake system which utilizes the stock air box but uses a less restrictive intake pipe. my mileage shot back up and when i stomp the gas pedal now that thing takes off like crazy and and Im rolling on 285/70/R17 BFG mud terrains. avoid exposed air filters if you need a cai, they do more harm then good
