TRD Cold Air Intake (PTR03-89100)  Fits 2010 – 2018+ 4Runners

Part number (PTR03-89100) TRD (Toyota Racing Development) cold air intake system is a genuine OEM Toyota part and carries a factory warranty through Toyota parts of TRD USA.

The next up in competition would be the AFE or K&N.

TRD Cold Air Intake (CAI) 5th Gen 4Runner - Filter and Box

Most of this post is going to be straight information on the actual intake specs. If you want to information from a true performance overview, check this page out.

Keep in mind that we already have a cold air intake on the 4Runner from the factory.

So why an aftermarket intake?

By bringing cooler, denser air into the engine, your 4Runner will run much cleaner and cooler.

This system features a low-restriction air filter that is housed in a special molding to keep air flowing tighter and cooler.

The TRD CAI is a great addition you can make when it comes to aftermarket engine parts and performance.

What the TRD Cold Air Intake Features

TRD Cold Air Intake (CAI) 5th Gen 4Runner - Service Filter

General Features

  • 4.0L V-6 Engine
  • Emission Legal in all 50 states.
  • Dyno-Tested
  • Increase HP Gains
  • Increased Torque
  • Superior Power and Performance when coupled with Exhaust
  • Enhanced Airflow
  • Increase Fuel Efficiency
  • Reusable/Washable Air filter
  • High-Flow/Low Restriction
  • Vacuum Indicator that monitors filter Efficiency
  • Indicator for Service – vacuum indicator that indicates when the intake/ filter should be serviced.
  • 1 Year Toyota Warranty

Benefits of the TRD CAI

TRD Cold Air Intake (CAI) 5th Gen 4Runner - Filter and Box

  • Lower restriction means more power and higher energy efficiency
  • High dust holding capacity means cleaner air to your engine and more power
  • Environmentally friendly, one filter for the life of your vehicle, simply clean and re-oil rather than replace
  • High heat resistance to extreme under hood environment
  • High-strength polyurethane seal material provides structural integrity for high load and vibration conditions
  • Designed using OEM parts for Maximum CO2 air filter housing
  • Surgical gauze filter media is supported by woven aluminum mesh to prevent pleat flutter and dirt migration
  • Contrasting colored oil ensures proper distribution

Increasing Horsepower

Adding a TRD CAI  will give you anywhere from 5-15 additional hp when installed and combined with other aftermarket accessories. If you are installing a CAI, you may also want to look at an exhaust system.

There are many other factors that go into producing more hp and they range from getting an aftermarket exhaust, cold air intake, air filters and of course a supercharger. The supercharger will obviously give you the biggest power increase.

The AFE Vs. TRD Cold Air Intake

COST

  • aFe 54-81932 Magnum FORCE Stage-2: $500
  • TRD (PTR03-89100): $475

WHAT THEY SAY

  • aFe produces 10 hp. 15 lbs. x ft. torque and outflows the factory intake by 34%.
  • TRD produces increase hp and torque (yeah, they don’t say much)

WHAT THEY SAY, EXACTLY

aFe: The housing features auxiliary inlet duct for better airflow as well as an attractive black aluminum cover that provides ready access to the filter for servicing. This system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance.

TRD: Developed using OE Engineering Information. In this case, that’s important because the mass airflow sensor – a critical component of the engine management system – is located in the intake area and must be accommodated in the design of the air intake.

WHAT SHOULD YOU BUY?

The general consensus is pretty close in a back and forth battle of which is the better intake. Most owners have either a TRD, aFe or K&N. It is a close battle between these. I think it comes down to personal preference on look and sound. All of these have a louder sound than stock, increase power, and generally work as advertised.

Emission Compliance

Emission Compliance Sticker - TRD Intake

UPDATE: See compliance sticker above. This came in from Blake and he had this to say:

“I didn’t even know it was compliant. I got the intake, installed it maybe a couple weeks ago, then yesterday another letter came from the dealer with a copy of the invoice that said the sticker was mailed separately, and it happened to be in that letter from the dealer. Didn’t ask for it, it just showed up from them.”

From the Original Post:

For 2010-2018+, Toyota has changed the emission compliance information on the CAI. A new process has been implemented by Toyota which means there is no longer a need for the emissions label which is typically included in the performance CAI for the 5th Gen and FJ cruisers.

We are located in California and will not be using an emissions compliant label. If your state requires an emissions compliant label, one may be ordered through Toyota dealer or the Toyota materials distribution center at 310-468-9800, or mdc@toyota.com.

The TRD CAI has received 50 state emissions compliance via the California Air Resources Board or CARB. Not all states require the emissions compliance label but TRD does recommend ordering one.

To receive the proper emissions compliance label for the TRD CAI please order MDC part number 00602–35120. Also, proof of ownership may be required, so you may need to prove that you bought the intake from an official distributor.

When I go on the TRD website to search for TRD parts for my 2017 4Runner TRD PRO it says the CAI is not an option for 2017?? I am wanting to add this to my vehicle was just curious why its not listed as an option for 2017. Is there a difference between the 2016 and 2017? I would appreciate any info if you have it. Thank you. Your page is awesome!! Keep up the good work.

Hello,

I just installed the same kit on a 2016. The air box doesn’t seem to sit flush with the supplied filter. Filter is the correct part number. With the air box top on, I can see the red of the filter between the base and the top. Is this normal? Doesn’t seem like it. Everything is flush. Seems like the filter side wall is too high. Lid is on tight.

Are you sure this fits(PTR03-89100) a 2016 4runner looking up the part number it says it it does not fit onto a 2016 4runner.

Thanx bro. I will definitely check out the link. I have another question. It seems the TRD CAI (Cold Air Intake) for 2013 FJ Cruiser is abundant. Can you advise with authority that a 2013 CAI will fit on a 2016 FJ CRUISER? And, does it matter if your steering is right or left?

New kid on the block. I’m a half step away from purchasing this TRD CAI for my 2015 T4R Trail Premium that I purchased last week, but being able to pass the whole California Smog Emissions thing has held me up as most parts people at dealerships are just pencil pushers and don’t know any different (topic for another thread) here is what my research has led me to. The TRD website or TRDparts4U.com states part number PTR03-89100 is 50 State Legal for 2010-2011 4Runners, the dealerships I’ve contacted can’t find it in their system. I’ve seen a few videos… Read more »

So as far as sound goes, how does the TRD intake compare to the K&N?
Thanks Lee

I’m very far form a mechanical person. I do have a friend though who is pretty mechanically inclined. When talking to him about this, he said that: “The PCU determines gas and air flow as per the mapping grid thus they call it getting the PCU tuned to allow more air or gas to make more HP.” Essentially, the CIA or exhaust changes really won’t do anything to increase air intake as the computer dictates that. The PCU would need to be reprogrammed or tuned in order to open that up. I likely will change the exhaust either way to… Read more »

Looking forward to the K&N CAI review! I live in Florida so emissions isn’t a concern (which isn’t necessarily a good thing, but that’s another discussion). Just bought my 1st 4Runner – ’16 SR5 FWD w T-Force – and am seriously considering the K&N intake as my first mod.

hi I came across this article trying to research the model number for a try cold air intake for a 2014 fj cruiser ( last year made for the US) will this model PTR03-89100 be able to fit my Fj ? thanks in advance for any advice

It seems as though everyone has been out of stock on these for a few months now. Does anyone know when they are expected to available or if this delay is due to an updated version in the making?

William Tucker

Eric I was told by my local dealer, Jay Wolfe in St. Louis, that the part will be available June 20th, 2018 and will be, he says, for the newer 4Runner models and specifically my 18 Off Road.

Hey Brenan, besides the slight increase in power, do you get any gains or losses in fuel economy?

Also, have you heard of anyone having warranty issues with these when getting their vehicle serviced at dealers? Maybe it has to be a TRD one? I have a 2018 and of course don’t want to do anything detrimental to the warranty.

Brian

Man Toyota seems pretty confused on this part. My local dealer looked up the part number and warned me their system says this part is only fitting a 2010/11 FJ and that if I install it on my 2016 SR5 to do it at my own risk blah blah blah. Some other FJs have this issue… I mean I am doing this one or the K&N? I would prefer TRD. Thoughts everyone?

William Tucker
Guest

I would never trust myself to do any mechanical work, thus I rely on info from people like Brenan, my dealer had same initial response as yours, but they were willing to do the work, they reported no complications, the part fits and performance gains are noticeable

Question on CAI’s in general. There are a lot of write ups about the computer compensating for larger CAI’s. Everything from the CAI only work on WOT, their is still a restriction of airflow when you get to the throttle body/intake area, engine will run lean and wear out faster all the way to they only thing they are good for is sound. Thoughts on all those arguments? Are we really wasting time and $ for a great sound and something that looks sexy? I also assume if you eventually go Mag SC, you would remove the CAI, or would… Read more »

Brian, the short answer really is…Yes, it’s a waste with an electronic throttle controller…unless you are getting a snorkle

Brian
Guest

Why does the snorkel make a difference ?

Nick
Guest

I should have specified – You won’t see any real HP or MPG gains from a snorkel either, but, You will be able to Ford the River Oregon Trail Style, which is definitely an overall performance enhancement in its own right in my opinion.

Just installed CAI on my 2015 Trail Prem after a 3 month +/- wait for delivery. Sounds much better but not obnoxious, seems to have a little more power – less pedal required on interstate inclines. Install was pretty straight forward, just go more by the step-by-step in this website than the instructions that come with the intake. Biggest improvement was the Pedal Commander, which made the 4runner much more responsive. As for MPG, I am used to a constant 18.1 mpg. Haven’t driven far enough yet to get a stable reading but am staying above 18 and am still… Read more »

I talked to Gary at the parts Dept. in Roseville Ca. (where I bought my 2019 TRD ORP) and they gave me a part number of PTR03-35160 any idea what the difference is between that and the PTR03-89100?

I see both listed online but of course nothing is listed for a 2019 (yet)

I wanna get the TRD Pro CAI on my 2015 SR5 but no one I know seems to know how or where to obtain the CARB decal. I tried the website in the thread and she referred me back to the dealer. Now the dealer is telling me they’ve never heard of this before. I’m near SF and have heard that CA will give a visual fail if you don’t have the CARB sticker. Any help is greatly appreciated!

If anyone in CA has recently obtained the TRD CAI and CARB sticker (for use with a 2018 4R or similar) please let us know (details appreciated)
