Cold Air Intakes Mythbusted

This may be old news to some of you, but very interesting...

Of course there is no comparing the "Blue ****" with a Raptor, but their approach and logic seems sound to me

 

[Hockster]

Yep sure is

 

[Chrisandalex1]

Wow. In our trucks we should be more worried about clean air intake.

 

[Ruger]

Okay, at 2:24 one guy grabs another guy's ****. What kind of "performance" are these yahoos really interested in?

At 5:50 they happen to mention that the test car is turbocharged. Is it possible that the results may vary if the engine is naturally aspirated, as it is in the case of the Raptor?

This "test" is entirely seat-of-the-pants. The first "pod" filter they test is the opposite of a CAI, as it is breathing air from under the hood. The second is a jerry rigged affair with at least three feet of hose. The third is a "cover" that's nothing more than a sheet of plastic. Where's the AIRAID, aFE, Volant, etc? Do these guys actually know what a CAI is? If so, why didn't they test them? And why didn't they test them on an naturally aspirated vehicle like the vast majority of vehicles on the road?

This is utter crap.

All it shows is that Nissan did a very good job on a car that is sold as a high performance boy racer.

This test is BS. Car has a turbo and CAI from the factory, as stated in the vid. It's also a small engine. No correlation to to a large displacement power plant.

Mind you, I'm not saying CAI have value, (I do believe they do and run an Airaid in my Raptor), but this test doesn't prove anything.

There I go again. Getting things all mixed up. Ford Raptors come from the factory with a CAI. So when we replace them, we are believing that the new part does a better job than stock. Same job, just better.

that was a retarded test. they are still running thru the installed intake tubing in the car. sticking a tube on the end of the existing intake would obviously not improve anything. pulling the headlight to let more air in wont help with the car sitting still without fresh(cooler) air being forced into it from driving....


oem intakes try to muffle the intake noise like a muffler on an exhaust. so i believe that also restricts flow as a muffler does.
remember all an engine is, is a big air pump.

also no tuning for the intake was done. there is a thread here showing dyno gains from an intake on a raptor. not sure what better proof we need. he took off the oem intake and put on a CAI and it gained power. thats a better test than rigging up some frankenstien air intake that no one would actually use. this test can also greatly fluctuate from vehicle to vehicle. my DD has a 1.8 mazda motor. the stock air box is very restrictive and if u get rid of it for a cone filter it is dyno proven to gain a few horsepower. even mor with "ram air" setups like vented headlight lids and turn signal intakes. then my last truck a GMC 6.0 LQ4 had a good air box and a very restrictive intake tube. lots of people just changed the tube and used a better drop in filter and got same results as guys (like me) with CAI.

my guess is on these trucks if u were to just change the tubing and use a better drop in filter it would have similar gains to CAI. i think the plumbing is the most restrictive part.

i run a CAI for the performance gain and the donaldson filter which is among the best filters in the industry

I-Intake

dont even get me started on the HAI-HOT Air Intake either. at least on our trucks i personally proved this wrong...

 

[RLTW]

Lol, that was a joke, i want my time back.

 

[6.2]

I still want to see dyno results with ONLY a CAI on a raptor. No tune, no exhaust, no nothing, aside form a CAI.

90% of CAI kits ive seen are open, as in, they let warm engine air in. nothing "cold" about that.

in my eyes, it depends on what the air intake from factory is like, as to how beneficial an aftermarket intake will be.

90% of cars will benefit from a high flow filter, but the $300+ you spend on that CAI wont gain you anything over simply swapping the filter.

I may get crucified for this, but oh well.

CAI's are snake oil. just swap your filter. same shit, but cheaper.

as for the sound, sure, it might sound louder, but that doesnt mean its faster, or has more power.

Didn't watch video but reading the post aobut the car being turbo charged.... air intakes on turbo engines will absolutely provide huge gains compared to anything naturally aspirated.

The only restriction of an air intake system on a mild mannered engine such as the 6.2 is the filter unit itsself and or there being turbulence created at a certain throttle position/rpm where the vaccum is tumbling the air and creating pocket voids into the intake manifold.
I'm not saying you can't get a 5-8hp gain with a system in our trucks, just that you not going to get 15-30hp on a turbo. Same with exhausts on forced induction are going to yield HUGE gains where na engines maby 8% max
