Air intake or replace air filter?

Hey guys,
So my 2017 sport reach 30,000 miles one thing i wanted to do is replace the air filter. Been searching around and notice people been putting trd cold air intake and kn air intake.

My question is. Is it worth it to replace the whole system instead of just the air filter? I do want somehing that will sound a bit more meaner than the stock. For those that have install the trd or kn air intake. Do you notice any difference?
Thanks

 

Not being a dick, but search cold air intake, there are probably a hundred of them and it always starts by someone asking same type of question you just asked and devolves to people posting that your truck already came with cold air and you must be stupid to spend money on it etc etc....then someone who has one will say they picked up power/throttle response etc...then they get called an idiot....it just goes down hill quick. Just be warned, and good luck.

 

END THREAD/

 

I hate to say it that way but I haven't seen one constructive cold air thread, just wanted him to know that before hand, Idk why that is such a devisive topic but man it is, and most get brural.

 

You are 100% correct

 

Yea youre a dick. Ive search it couldn’t find any topic on what I specifically asked thats why i started a thread.

 

Ok well have fun with this one

Perfect example

 

Some intakes can create noise . In olden days one just flipped the air cleaner cover to do it . It always sounded awesome with a V8 and a manual transmission . It sounds to an old school ear with a V6 or a strait 4 , especially with an Auto trans - crappy at best . I believe this 3.5L auto combo would be much better liked if it were silent ! High revs and shifting would not be noticed as much and could rev to where the power is .
Like all above have said and in all threads before , save your money unless you like V6 noise .

 

Search function sucks on a lot of sites.

That said, probably shouldn't say peeps that respond are dicks. Even if they are.

The truth is, if an OEM could find any more HP's by simply making a molded plastic elbow, they would. They have a great deal of resources at their fingertips, and the stock unit is what they chose. Therefore, I doubt that there will be too many options for actual HP gains, or improved efficiency.

 

This is the part I disagree with. Most CAI are NOT California compliant. OEM is forced to make a decision to best suit the core demographic of people who will buy there vehicle.

An aftermarket intake deletes the factory resonator and is much louder. By installing an aftermarket intake you may see some marginal gain, but it probably not worth it for most people.

 

Since the OP thinks you are a dick, let me respond in typical fashion:

"Your truck already has a cold air intake. If you want to change just for sound then knock yourself out, because sound is all you are gonna get. I don't care what you do though, you can't get a good sound out of a V6 unless it is running at 12K RPM.
You also won't get any better mpg either. Nor will you get any more power, unless at wide open throttle and then it is just a few hp.
Toyota spends millions on R&D every year, ya think if a ten dollar part could increase efficiency that thwy wouldn't already be using it?
It's your money spend it like you want. You will get the bling factor when you open the hood. That's it."

How's that for a standard response lol.

 

Now it's definitely End Thread/

 

Slapping on an aftermarket intake COULD raise the overall power by a HP or two (note: rare cases. Most only just make your truck sound louder). However, I’ve noticed with most intake systems, torque down low takes a hit. With an already anemic engine (tq wise), I don’t think switching out the OEM intake is a good idea. Usable torque is compromised.

 

Do it for the sound it won't do much else

 

This is such a tired ass argument... Why do racecars have different intake systems than road cars? Even more R&D? No, the fact of the matter is that Toyota is forced to cater their tune to the lowest common denominator customer. Grandma and Grandpa don't like vrooms.

 

Race car engines are torn down after each race. Even amateur racing cars are rebuilt on a regular basis. Their intake systems are not meant for daily driving.

 

Lol i posted a "generic" response, not how i think exactly.
However, i can tell you why it isn't a tired ass argument and why your example is like apples to pottery in comparison.
Right now, if you run your stock air filter, you get "X" mpg and "Y" power. If you REMOVE your air filter, you will get the same mpg and the same power, excepting at wide open throttle, where you will get a bit more power.
This is not the old days. Your ECU controls the amount of air gets through the intake. If more air happens to get through, the ECU will simply throttle the air flow back to normal, meaning the mix will be the same and power too.
In order to take advantage of more air, you need a different tune to account for the additional air. So just adding a different CAI or filter will do nothing.
Now, why does Toyota do what it does? Efficiency, plain and simple. Pretty sure that if more power and efficiency could be simply gained with a twn dollar part they would figure out a way to get it by CARB.

 

In the defense of wanting to add one also, it really isn't worth the money, only time I've gained power from a CAI is on a WRX, my JK didn't gain anything except for clearance when I sink in water. best to just run a better filter and save the cash for other parts.
