Cold Air Intake?

Hey guys, I'm new here, I apologize in advance if this thread is out of place.

But I wanted to get some input and thoughts on cold air intakes; are they worth it? are there any cons to having one (damage to engine, etc.)? any brand recommendations (knn, etc.)?

Thanks!

From what I read, not really. I bought and installed air raid CAI before reading that they are not necessary. I kind of agree, I didn't feel much of a power gain, the little that I felt was probably from the tune. When I had my old 2006 V6, those you could feel a difference right away.

CAI doesn't help much unless you have a larger exhaust to move all that air out, on the other hand cooler air entering the intake helps your car burn fuel more efficiently, my guess is any mustang owner will take 1-2 more mpg, that makes it worth it.

I'll agree with the first part of your post that a "CAI doesn't help",

The OE intake is a better Cold Air Intake over any of the open element intakes that sit inside the engine compartment as it pulls in ambient air.

Cold air doesn't increase fuel mileage, actually it'll cause a drop in mileage since cold air is more dense than warm air you need more fuel to maintain the proper A/F ratio. That's why everybody likes likes those cold track days with their negative DA's .


>>> thoughts on cold air intakes; are they worth it? are there any cons to having one (damage to engine, etc.)? <<<

You'll need a tune for a CAI or you'll risk running lean and popping a piston (specially #8).

There are some 'no tune required' CAI's, but they're a waste of money unless you just want the look of an open element CAI.

Thanks so much for all the information. If I were to do a CAI I would be doing it mainly for the sound and looks. Does anyone know if the hood vents on a 2013 will be an issue for an open CAI? Or do they stay dry? I just don't want to hydrolock my car.

Thanks!

They will increase throttle response a little. And the sound the throttle makes. Each CAI has its own sound to it. I have an SR Performance which is basically a BBK without BBK logo on it. It can be installed without a tune, but it makes a whistling sound at low RPM throttle if you don't tune it. Just a warning.

Like I said, they all sound different, but they will increase throttle response and maybe upper RPM horsepower.

Also- hood vents should not cause issues. I have a Boss 302S grille which just has netted holes/openings where the GT fogs used to sit (which allows more air into radiator and engine bar) and everything is fine. I have the Boss 302 fascia, so my fog harnesses now run down to smaller fog lamps at the bottom of the car (like a Boss). With this grille, though, the car runs cooler and during the winter, the ECU likes to throw a code if you get a good gust of cold air into the engine bay stating that the thermostat is not opening correctly.

This is correct, but it is also incorrect. Yes- the thermostat is not opening in the normal amount of time. But it is not due to a malfunction with the thermostat- it is due to the fact that the car runs cooler and takes longer to reach that temperature of which the thermostat opens. If you have a tuner like I do, it's not a big deal. You just clear the code and go on with your day. Just more food for thought. EFI has a lot of funny stuff that carb'd motors didn't have to deal with, so it takes some experimenting and sharing of information to know what each change will do.

i have a '14 and when i had my airaid on, my car stalled out about 4 times due to water before i could get home and change it back to stock. I got out in the rain and dried everything with a towel i had every time. It was mainly the water drops on the MAF causing the issue.

I went back and forth on purchasing a CAI for my 2013 GT and after much reading on several forums I decided to stick with the stock air box. I did add an Airaid intake tube to replace the stock intake tube the Airaid tube is supposed to flow 400 CFM more air over stock? And it will not have the noise canceling chambers that the stock intake tube has this could be a plus or a minus depending on how you feel about intake noise. As for water getting in the vents of a 2013 or 14 hood yes it can happen I tested mine with a significant dump of water and I would only get a few drops of water but for me that's just too much I don't want any water near my intake! I also purchased the small foam water blocker from JLT to cover a small area of the air vents over the intake it works ok but really needs to be silicon in to be real effective and I did not care for blocking off the vents. The cover that Airaid sells as a rain shield is a bit of a joke why bother just use the stock air box problem solved! I also take issue that if the seal was so good on the Airaid cold air intake you should not have a water issue. I am told the Steeda cold air intake seals to the hood better I'm not sure about the other brands. I did not feel overall the gains were worth it adding a CAI and frankly I would have always worried if I got caught in a big rain with my "13" and water saturating the intake filter no worries with the stock box.

Thanks for all the input. I think I'll just stick to the stock airbox for now.

There are so many CAI's out there and people keep buying them. I wish someone would do a correct video showing a stock 5.0 mustang on the dyno with the results. Now put a tune on the stock Mustang with the stock air box. And show us the results. And finally put the aftermarket CAI on run it on the dyno and show us the difference. NOBODY WILL DO THIS!!!!! The manufactures will not show us that you are wasting your hard earned money on a CAI.

Going for looks and sound? Steeda.

Has a nice whistle and looks the best under the hood. Function? Eh'... I couldn't tell a difference. Even after I put a larger inlet tube and wider throttle body on. All benefits came from the tune IMHO

+1 on the Steeda, its a quality piece. I ran it before I went the procharger route. Not sure about the gains but it looks nice and has a good sound to it like ChiZ said. IF you're concerned about the hood vents letting water in JLT sells a piece of foam that will block off the part of the hood vent that is over the CAI.
