Why It Works for the Camry 2.5L
-
The factory intake setup on the Camry 2.5L is adequate for daily commuting, but it restricts airflow under higher load conditions. The 21-855C replaces that setup with mandrel-bent aluminum tubing and a high-flow synthetic filter to improve airflow and throttle response.
-
Filter housing is redesigned to draw cooler, denser air from a more optimal location with a heat shielding design—resulting in more efficient intake charge and better performance.
-
Dyno figures show estimated gains of approximately +8.7 HP @ ~6000 RPM in tests for this model.
This Performance Air Intake System allows your engine to breath more air compared to the restrictive factory air intake housing. It is designed, tuned, and dyno-tested to produce more horsepower and torque. The cone-shaped AEM Dry flow air filter is made from an oil-free, synthetic filter media that can be used for up to 100, 000 miles before cleaning is needed (depending on driving conditions).
Key Features
-
Washable, oil-free AEM Dryflow synthetic air filter media, rated for up to ~100,000 miles between services (depending on driving conditions).
-
Mandrel-bent, powder-coated aluminum intake tube designed to reduce turbulence and intake restriction.
-
Heat shield with edge-trim lining to help isolate intake from engine bay heat and maintain cooler air intake temperatures.
A custom shaped heat shield with edge trim lining is included to keep engine bay heat from the air intake. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system is backed by AEM’s Lifetime Limited .
Performance Benefits
-
Improved throttle response—engine breathes freer so you feel the difference.
-
Better mid-range pull and improved performance under load thanks to denser air charge.
-
More aggressive induction tone—your Camry sounds less “sedate commuter” and more “intentional driver”.
-
High-quality reusable filter saves money long-term and reduces maintenance hassle.
Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the vehicle applications to determine the legal status for each vehicle.

This is my first full AEM intake system, I’ve had a K&N intake on a previous car and this system is comparable. I enjoy the fact that the AEM provides dyno results to show that the system actually makes HP and torque, and exactly where it does. The instructions leave something to desired, but if I can figure it out, almost anyone can. The install took me about an hour and I’m not very mechanically inclined. I do have a small complaint about one of the bungs not screwing in cleanly (I tried multiple times), but it hasn’t seemed to cause any actual issue with the performance of the system. In terms of noise, expect it to be fairly loud under load, especially if coupled with an aftermarket exhaust. The butt dyno says that it’s given some power and responsiveness. Not the least expensive system, but I’m happy with my purchase.

It does have sound like exhaust but its a great product and it will help you vehicle very much i have got much better throttle response with this intake i will give it 10 out of 10 but about the price i am giving it 6 out of 10 its a little pricey but over all its a great product.

Intake was easy to install with clear instructions. My 2019 i4 Camry SE sounds so much better on acceleration. Gives it a nice growl as the air is drawn in and masks some of the direct injection noise when that’s active. All CAI makers show dyno charts with increased HP. I’m sure a bit of additional air drawn in surely helps; but any noticeable difference on throttle is not felt as most HP is added on the top end. It’s pretty rare I’m reaching 5000rpms in daily driving. I don’t really pay attention to MPG as I live close to work and fill up once a month so not sure if that’s increased or decreased. No aftermarket tuning done either. Car is stock less this addition. Solid investment just for the sound improvement alone though.

Kind of simple to install all the parts & instructions where all there with quick shipping. Only thing it is kinda pricey to what you actually gain but very satisfied with purchase

When you reconnect the negative cable first do switch your car wait a seconds till read the upgrade and then start the engine will be app per something with the battery disconnect ur battery and reconnected same process switch, wait and start engine.

Been using this for a year now, loving the roar at high rpm. Make sure to clean it once in a while
Shanon –
Works great and easy install! Adds a nice sounds and better throttle response.
Antonio Perez –
Removed system. Makes your vehicle sound like you have an exhaust leak. Did not like the results at all. Not sure it’s worth what they ask for the system.

Product was well packed and reached before its time but Shame the air filter was missing in the packing had to return it back
