TRD Cold Air Intake (CAI)
TRD Cold Air Intake (CAI) 5th Gen 4Runner & FJ Cruiser
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.

5th Gen 4Runner TRD Intake
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
- 4.0L V-6 Engine
- Emission Legal in all 50 states.
- 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
- 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
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
- 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.

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 email@example.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.
