TRD Cold Air Intake (CAI) for 5th Gen 4Runners

The Dyno-Tested TRD Cold Air Intake System

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

The TRD Cold Air Intake system is a Dyno-Tested intake system that is sure to beef up your torque and hp gains. By bringing cooler, denser air into the engine, your 5th Gen 4Runner will be running much cleaner and cooler. The TRD Cold Air Intake System features a low-restriction air filter that is housed in a special molding to keep air flowing tighter and cooler.

One of the special features of the TRD Cold Air Intake System for 5th gen 4Runners is that is has a vacuum indicator that indicates when the intake/ filter should be serviced. It’s awesome. The TRD Intake system for 5th Gen 4Runners is one of the best additions you can make to your 4Runner when it comes to aftermarket 5th Gen 4Runner Engine Parts.

Increasing Horsepower on your 5th Gen 4Runner

The TRD (Toyota Racing Development) Cold Air Intake System is a force to reckoned with when it comes to increased horsepower (hp) in your 5th Gen 4Runner. Adding a TRD Cold Air Intake (CAI) System to your 4Runner will give you anywhere from 5-15 additional hp when installed and combined with other aftermarket 5th Gen accessories.

If you are making to move to the TRD Cold Air Intake, you will likely want to opt for a TRD 4Runner Exhaust System or look at other aftermarket exhaust systems like the 5th Gen 4Runner Magnaflow Exhaust.

There are many other factors that go into producing more hp in your 4Runer and they range from getting a 4Runner performance chip, aftermarket exhaust, cold air intake, TRD 4Runner air filters and of course a supercharger. The supercharger will obviously give your 4Runner the biggest power increase.

Supercharging a 5th Gen 4Runner?

By converting your 5th Gen 4Runner’s engine to a forced induction, your engine will utilize a compressor mounted on the intake. Which ultimately superchargers or turns your 4Runner into a turbo engine. As of now, Toyota and TRD (Toyota Racing Development) have not developed a supercharger for the 5th Generation.

Toyota keeps saying they are going to introduce a supercharger for the 5th Gen but we have not seen one yet. Hopefully, good things to come soon on the 5th gen supercharger for 4Runners.

The AFE Vs. TRD Cold Air Intake for 5th Gen 4Runners

This is the question for many 5th Gen 4Runner owners. What is better, the AFE intake or the TRD intake?


  • aFe 54-81932 Magnum FORCE Stage-2 Cold Air Intake System (10-15): $500
  • TRD (PTR03-89100) Cold Air Intake System: $475


  • 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)


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 intake 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: The TRD Air Intake Systems are 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.


If you are buying a cold air intake for your 5th Gen 4Runner, I would personally have to say TRD, only because it is made by TRD. However, we did read that aFe makes the TRD Intake. I know, strange right.

The forums are pretty close in a back and fourth battle of which is the clear winner. Most 5th Gen 4Runners have either of the two; TRD or aFe. It is a close battle between the two. I think it comes down to personal preference on look and sound. Both have a loud sound, both increase power, both look cool.

All in all, we would still opt to buy the TRD Intake. Eventually, couple that with a TRD supercharger and you will be smashing down the freeway and mobbing over trails.

Emission Compliance TRD 5th Gen 4Runner Cold Air Intake

For 2010-2017+ (5th Generation Models), Toyota has changed the emission compliance information on the cold air intake. 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 air intake kit for the 5th Gen 4Runner and FJ cruiser’s.

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

The TRD performance air intake kit or cold air intake 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 performance air intake kit or cold air intake please order MDC part number 00602–35120. Also, proof of ownership may be required, so you may need to prove that you bought the TRD cold air 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.

    • Brenan - Trail4R

      Angie, good question.

      If your 2017 4Runner has the v6 4.0-liter engine, it should fit just fine. We have a 2014 and a 2016 4Runner, they both have the same engine, I don’t think there is anything different about the 2017. Pop your hood and make sure your engine bay looks like this (4Runner Intake Install – Refer to Step #1). If everything looks similar, you should have the V6 4.0-liter engine in which the 5th Gen TRD intake should fit your 2017. I would call your local Toyota service center also to see what they say. Also, Toyota said that the same intake did not work for the 2014 4Runner (maybe CA state emissions??), but we clearly installed it and it kicks ass. In any case, if you are running the same engine with the same layout, I think you should be safe. Again, just check your local Toyota service center and see what they say.

      EDIT: The K&N is the only intake that is currently available for the 2017-2018 4Runner ( Good Luck and thanks for the kind words!

  • Benjamin Cox

    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.

    • Brenan - Trail4R


      For whatever reason (Maybe California Emission Standards – Amazon wouldn’t even ship it to California), Amazon and even the Toyota Service Center will say that the intake does not fit. I had to purchase it directly from an out of state TRD authorized dealer. With this being said, I am 100% certain it fits on 2014, 2015, 2016 and 2017. We own a 5th Gen 2014 TE (Trail Edition) which is installed here (TRD Step by Step CAI Install), along with a new 2016 SR5 which has the same exact engine layout. There is literally nothing different about the engine. Also, on Amazon, there are many different people that say they have installed on 2016 SR5 and TE (Trail Edition). Your 4Runner has a 4.0L V6 Engine (Same Engine). It will be a clean easy install. Go for it.

  • John LaPlume

    Talked to Toyota today, apparently they moved the air pump on the 2017 4Runner so this will not work. Hopefully they will come out with an updated version soon. John…

    • Brenan - Trail4R


      Good to know. Thanks for the heads up. Let us know if you hear any update on the 2017 4Runner CAI (TRD or any aftermarket Intakes).

  • Fern

    Hi – Was able to install this exact TRD CAI on my 2017 TRD Off-Road with a very minor modification. Nice clean install. Runs great!!

    • Brenan - Trail4R

      Yo Fern,

      Thanks for sharing. This is good news to many 2017+ owners out there who want to install the TRD Intake. Thanks for sharing your images through email. We will get these posted somewhere on the site to show that installing the TRD intake on the 2017+ is possible.

      Thanks again for sharing.

  • Robert

    The third sentence in this article has the word you and it should be the word your.

  • Walter Jeremy Golding

    I want to fit the 5 gen cai trd filter to my 2016 FJ cruiser… what must I do to purchase it from your site/or how do I purchase it.. Im despetate to purchase it.. please help.

    • Brenan - Trail4R

      We do not sell the TRD Intake. I would call your local Toyota parts department or check the link on this page. Or, there are a few online retailers that have it for sale. Check TRDParts4u. They might have it in stock.

  • Walter Jeremy Golding

    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?

    • Brenan - Trail4R

      I honestly have no experience with the FJ. I have owned 4Runners my whole life. Not sure about the 2013 Intake fitting on a 2016 FJ. That would be a good question for your Toyota Service Center.
      Cheers! – Sorry I can’t be more helpful in the FJ department.

  • Jeremy

    Will this fit my 2018 Toyota 4Runner TRD Off Road if it does where can I purchase one

    • Brenan - Trail4R

      Yeah, this intake was installed on a 2017 4Runner. See the post here (2017/2018 TRD 4Runner Intake). One of our members installed this on his 4Runner, which was a 2017. 2017 and 2018 have the same engine layout. You should be good to install this TRD Intake on your 4Runner, but you may need to do some adjustments. Also, there is nothing wrong with the K&N intake. We are actually buying a K&N INtake for our 2016 4Runner to see the difference here pretty soon.

  • Andre

    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 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 of this being installed on 5th Gen 4Runners, you state that it will fit on 5th Gen 4Runners so “we” know that it fits. The big mystery seems to be why don’t the dealerships get on the same page with this information? You’d think they might want to sell $375 parts like hot cakes right???

    Anyway, here is a link to the actual California smog gods that clears 4Runners up to 2014 for this intake that was reviewed by their Mobile Source Operations Division in 2013. I hope this helps.

    It’s a holiday today, so I’ll contact TRD direct tomorrow and see if they have any updates. BTW, so far I added a Magnaflow cat back system last week and I’m loving it!

    • Brenan - Trail4R

      Awesome information. Thanks. Yeah, I have heard of a few people passing smog just fine with the TRD intake. We are not up for smog for another two years but I am sure we will pass if others are passing in California as well. We will see what happens. I would pull the trigger but that’s just me. Just save your stock airbox just incase.

      • Andre

        Hey Brenan!

        Thanks for the advise! I was also thinking about a drop-in K&N filter as another option since that would probably get me nearly half of the horsepower of the TRD CAI for only 50 bucks. HA!

        I know the tube must flow better without those noise chambers, but how do you think the carbon filter in the top part of the housing affects air flow? Looking for more justification for this purchase. I know we’re not building a race car here, I’m thinking of efficiency. Speaking of which, have you noticed a difference in your MPG?

        • Brenan - Trail4R

          We actually just bought the K&N filter for my girls 4Runner just to review it. It should be here tomorrow. After that, we will buy the K&N intake and then see what that one is all about. The carbon filter is designed to meet higher emission standards. When you shut your 4RUnner engine off, any remaining vapor in the intake manifold will stay in the manifold and travel backwards towards the inlet of the air box. This remaining vapor get’s absorbed by the carbon portion of the filter. I wouldn’t count on a filter doing much for HP gains, but we will see. For MPGs it all depends on how you drive. If you drive conservative, then you can expect to see gains. If you have a lead foot, then expect the latter. I drive my 4Runner pretty hard with the exhaust, intake and now the throttle response controller. So, my MPGs are pretty low, but they did go up after installing the Pedal Commander. I also have 34″ tires and that does not help.

  • pete

    I share your passions, 4Runners, Nature and photography. Thanks for sharing your knowledge. Good luck and may the 4Runner take you places few have gone, to see things few have seen.

    • Brenan - Trail4R

      That is so awesome! I am not the best photographer nor am I a 4Runner “expert” by any means but they are two things I definitely love.
      Cheers, Pete and to you as well!
