Cold Air Intakes. Debunking false claims.

A engine is basically a multi cyl air pump , so the more air you can efficiently put into it and then force out of it you'll make more hp !!!

 

scotty kilmer does understand the uselessness of a CAI on a fuel injected engine tho

 

that's only true in a carbed engine, not an EFI engine

 

It's true for both, but the stock intake isn't enough of a restriction to make a difference in this case. Now with FI it would.

 

the 3rd GEN already comes from the factory with the best designed and functional CAI already in it, why waste more $$ on a debunked aftermarket system when u already paid for the best for the truck designed Toyota engineers for the 3.5l engine

 

the stock efi computer and Mass airflow sensor is designed to operate optimally on how much air the stock intake system gives it, not a bolt on system that only introduces hot air from the engine bay

 

What about in a few years when the aftermarket catches up and starts making hiperf parts for it like cyl heads , cams , headers and bigger throttle bodies

What will you say then ???

 

No, if that were true it would be PGMFI and no MAF would be required. The MAF tube is sized for the sensor to properly reference the airflow over it. But that doesn't mean you cannot flow more air through that space, at a certain point it will become a restriction. But if you couldn't flow more air then things like superchargers and turbos wouldn't exist. You can put a less restrictive filter in and presumably see gains (however small and useless they may be for their dust intake tradeoff). The EFI adjusts to the volume of air supplied to it.

 

i'll say its a truck not a drag race car, I don't need it

 

Bill, I think you might want to read how modern EFI systems tune their mixtures and what all the sensors do.

 

those minute gains made by trying to force in more air into system already tuned to use X amount of air from the factory is not worth the effort in the stock engine platform, you will never feel it.

 

Yes, I said that already, I was merely correcting your understanding of how a modern engine management system functions. You made it sound as if they cannot adjust to an increase in airflow. And they don't force more air in unless there is a supercharger or turbo, it allows the engine to DRAW air with less restriction. They have lots of adjustment, I threw a Supercharger on an old ass taco last week and saw major gains from it haha. In this particular case it is absolutely pointless to throw a hot air intake with a freer flowing filter on a third gen, but at WOT they may see a whole 2HP haha

exactly 2hp hahaha

 

Again Bill, I am not arguing whether these stupid things work we already know they make a very insignificant change very high up in the rev range at the expense of filtration. I was arguing your explanation of why they do/don't work

If HP gain is what you're after, and you believe that more/better air flow is the answer, go and buy yourself a supercharger. Shove that air into your cylinders! Whiiiiiiiiine!

 

Umm well Toyota does put them in the truck. The TRD performance intake comes with a TRD oiled air filter. And Toyota sells the TRD oiled air filter as a “performance air filter”

This is all I disagree with, it will operate (negligibly) better with one of these dumb CAI. These sensors don't give a shit what piping and filters are feeding them, if there's more air (however little) then they can adjust for it and you get more power.
