Did you know that Sequoia is like Tundra’s little brother? Well, it’s not particularly “little”, but it was, indeed, engineered on the full-size pickup’s original formula. These days, there are a lot of differences between the two nameplates. But, the powertrain is similar in many ways. That is exactly why in this post, we will focus on aftermarket air filtration systems for both vehicles.
But how does the best cold air intake for Toyota Sequoia and Tundra look like? And how do you find the one that meets your needs, budget, and fits your four-wheeled friend? Well, you can always let me do the heavy lifting! After weeks of testing in real-world situations, I picked the following three intake systems for you. So, go ahead and make you pick!

Best Toyota Sequoia/Tundra Cold Air Intake Reviews
1. S&B Filters Cold Air Intake for Tundra and Sequoia
What’s the number one thing that you expect an aftermarket air intake to do? To increase the airflow, of course, and S&B’s kit does exactly that. It also improves the MPG (miles per gallon) ratio, saving you hard-earned bucks in the long run. Next, thanks to a boost in air filtration, it provides better acceleration. You’ll feel that the second you start the engine behind the wheel of a Tundra or a Sequoia.
As for the installation process, most regular drivers believe that only a mechanic can handle that. Well, this cold air intake is very easy to mount/install and you won’t even have to do any tuning/calibration – the engineers already took care of that. S&B offers two different filters to choose from: a cleanable (lasts longer), and an expendable one. My only complaint has to do with the minor quality control issues. I’m talking about missing parts/hardware.

This air intake kit is a whole package. It’s equally good at increasing air filtration and boosting the performance (acceleration and fuel efficiency). And, it doesn’t require any tuning: just install it properly, and that’s it. You might get an incomplete package but this was only reported by a small number of buyers.
2. K&N Cold Air Intake Kit for TOYOTA Sequoia, Tundra
Durability and longevity are this company’s trademarks, along with reliability. They only produce quality replacement parts, and this air intake is no exception to that rule. It won’t break down in the middle of nowhere, that’s for sure. On top of that, it guarantees a boost in performance (true for both Tundra and Sequoia). Another standout feature is the excellent protection against so-called “contaminants”.
The list includes dust, debris, moisture, and more – everything that can cause harm to the powertrain. Now, personally, I like how this air intake makes the engine sound: aggressive and with an attitude. But, it’s louder than what I’m used to, and for some drivers that prefer calm, noise-free ride, this can be an issue. That’s the only significant downside, by the way.

The improved throttle response, extra “horses”, and outstanding anti-contaminant protection turn K&N’s cold air intake into a bargain. Market-leading durability and reliability are a part of the deal as well. It does make a whistling sound, however, which can be kinda annoying for some drivers (others might like it).
3. TOYOTA Cold Air Intake
And here we have the most expensive, but also the most advanced cold air intake you can buy for a Toyota SUV/truck. As the name suggests, it was produced by the company’s own engineers, which means perfect fitment is a part of the deal. And, it features a long list of high-end installation hardware (I’m talking about hoses, clamps, and more).
This intake kit is from the Toyota Genuine Parts line-up and won’t be hard to order to any of the US states. Overall, it doesn’t have any downsides in terms of performance, installation, and reliability. The high price is the only con. It can be a deal-breaker if you’re low on funds and need something simpler and less expensive. The quality and efficiency are unmatched, though.

Superior to pretty much all the other cold air intake systems, this kit by Toyota is a keeper. It’s rather expensive, but the OEM fit, easy installation, and high-quality parts + hardware make it worth every single penny.
Conclusion
No matter which vehicle you drive – Tundra or Sequoia – an aftermarket cold air intake kit will be a good purchase. It’s one of those can’t-go-wrong-with types of investments, as it will protect the engine and keep it “healthy” for a long time. The added powertrain bonus (extra horsepower, torque, and acceleration) should give you more incentive to cash in for a brand-new intake system.
Drivers with thick pockets and a taste for quality parts will probably go with Toyota. While the kit is pretty expensive, it’s OEM gear and will take no effort at all to install. K&N improves towing, protects the engine from “outside threats”, and guarantees a performance boost. With S&B, you’ll get premium build quality and wide coverage. So, which one is your favorite?
