Complete Overview and Installation of the Volant Intake on the 5th Gen 4Runner
The Volant Intake might be the perfect size for some, and it sounds great too!!
Coming in with a bigger airbox than the TRD Intake and a smaller airbox than the aFe intake, the Volant airbox sits right in the middle.
The Volant Intake has one notable difference over the TRD and the aFe, its RAM scoop. Do you see that large scoop covering the air injection pump? That is their RAM scoop.
We all know the 4Runner comes factory with a “cold air intake” so why buy another cold air intake?
Our factory intake has this massive clunky portion of plastic (intake resonator, and more officially a side branch resonator) that is designed to reduce the noise of the intake and improve efficiency.
The purpose of an intake resonator is to restrict airflow through the RPM spectrum and even more so through the powerband thus causing less intake noise (intake whistle) and hypothetically an increase in horsepower.
Why the Volant Intake?
It’s a complete kit that includes a closed filter box with dual air ducts pulling more air than traditional intakes, and Volants signature Pro5 filter.

- Easy Install
- Improve Engine Operating Temperatures
- Improve Horsepower and Torque
- Made in the USA
Also, a special not for everyone in California, this cold air intake is not CARB compliant.
There is no tuning required, just install the new airbox and you are good to go! It’s a simple process and doesn’t need an expert.
Coming Straight From Volant:
The intake utilizes a high-velocity venturi filter adapter which provides a smooth transition through the MAF sensor into the intake tube for a much-needed airflow improvement over the factory rubber tubing and resonator box.
Volant’s Airbox is larger than the factory unit and incorporates a larger opening to collect a higher volume of colder ambient air. This model includes a Pro 5 filter which gets reoiled every 10,000 miles and serviced every 50,000 miles with cleaning kit P/N 5100. With Volant you have an intake that delivers excellent horsepower you can feel and fuel economy that puts some money back in your wallet. – https://volant.com/
Installation & Tool Check
In this step by step installation overview, you will see how simple the install was compared to the other two intakes we have installed so far.
No rerouting of wires or assembling tight parts.
This is a complete plug and play intake that took under 1 hour.
Not all needed, just what I used.

- Milwaukee Screwdriver: Check Price
- Bent long nose pliers: Check Price
- Snap-On Light:

Pre Installation Step:
Before you begin the install you must disconnect the negative battery cable. Failure to disconnect the battery may cause a check engine light and/or damage to your engine. You also want to remove the engine cover before starting.
Step 1: Loosen the air duct to Throttle Body & Air Box
After removing the engine cover, loosen the clamp holding the air duct to the throttle body. Then, move over to the airbox, and loosen the clamp holding the air duct to the air box.
Step 2: Remove breather hoses
Using a set of pliers or even your hands, remove the factory 5/8 breather hose from the air duct (image left). Then remove the factory 1/8 breather hose from the resonator box (image right).
Step 3: Remove the factory wiring harness from the resonator box
Using a set of bent needle nose pliers, remove the factory wiring harness from the resonator box. Everything in life is easier with a nice pair of bent needle nose pliers.
Step 4: Remove Inlet Tube
Remove the bolt holding the resonator box in place and then pull the factory air duct and resonator box. Save in case the vehicle needs to be returned to stock.
Step 5: Disconnect MAF (Mass Airflow Sensor)
Disconnect the MAF sensor harness from the MAF sensor and then the MAF sensor harness from the top and back of the factory air box.
Step 6: Remove Air Box Lid, Unclip and Unbolt all Connections
Remove the factory lid and air filter from the factory airbox.
You should save all of these parts just in case you need to reuse in order to pass smog (especially if you live in California like us). Then remove the 2 bolts holding the lower half of the factory air box in place.
Save these factory bolts for reinstallation.
Step 7: Remove Resonator Bracket and Air Box
Remove the resonator air duct/inlet tube support bracket from the engine. Then remove the lower half of the factory air box. Again, save these parts in case the vehicle needs to be returned to stock.
Step 8: Insert new 1/8 breather hose
Remove the factory 1/8 breather hose from the engine (left) and save. Then install the supplied 1/8 x 16in breather hose onto the stock location (right).
Step 9: Remove and Install the MAF (Mass Airflow Sensor)
Remove the MAF sensor from the factory inlet tube and attach to the new inlet tube provided.
Step 10: Throttle Body, Air Box, and Ram Scoop Adapters
Step 11: Attach reducer to the throttle body
Attach the 3.5 to 3in reducer to the throttle body with the provided #48 clamp using a 5/16 socket or nut driver.
Step 12: Install the Air Duct/ Air Inlet Tube into Place
Slide the 4in hump hose and #64 clamps onto the filter end of the air duct and press the duct into the reducer.
Step 13: Attach Breather Hoses
Plug the MAF sensor harness into the MAF sensor and then attach the factory 5/8 breather hose to the 5/8 stem on the Volant air duct. Continue to attach the final 1/8 breather hose to the 1/8 NPT fitting on the Volant air duct.
Step 14: Inset Ram Scoop
Attach the 3 3/4 x 2.5in sleeve onto the RAM airport on the Volant box with a #60 clamp using a 5/16 socket, or screwdriver.
Step 15: Add Intake Filter and Tighten with Provided Clamp
Slide the largest clamp and provided filter into place inside the Volant airbox.
Step 16: Choose Lid “Volant” Color
Volant provides you with a few different color options to choose from. You can go with white, red or blue.
Peel back the color of your choice and place upside down on the Volant airbox lid.
Volant Intake Measurements
The first measurement is from the airbox to the weather stripping. About 5.5″ give or take the wiring harness below, that can be relocated though.
The second measurement is from the airbox to the firewall. About 10″.
How does it sound?
Deeper and more throaty than the aFe and just about on par with the TRD intake. Both the TRD and this Volant intake have a deep mean throaty rumble around a wide range of the power band (3000-6000 RPMs).
The Volant intake has a wider range to be heard and felt on the power band, which comes out close to 3900 RPMs and lasts until you let off, unlike the aFe, coming in hot and alive around a more narrow band (5500-6000 RPMs).
The Volant Intake sounds great, is easy to install and will be a great option for many drivers looking for that added driving experience.
Did it improve HP?
Without a Dyno, it’s hard to say what the exact HP gains were. It would be nice to see a Dyno straight from Volant but I guess we will have to wait.
My first guess would be somewhere in the 10 range and more than likely 5-7 depending on the exhaust you are running and whether are not you are willing to get the truck tuned. Hopefully, we will be able to upload a Dyno sheet from Volant directly here soon.
