The Best Cold Air Intake for Your BRZ

Your Subaru BRZ is sleek, nimble, and best of all — has a heap of tuning potential.

It’s fun to play around with BRZ modifications, as Subaru has gifted you with the perfect opportunity to build a performance monster. With a little tinkering, you can a heap of performance and enjoyment out of this little machine.

In this guide, we review some of the best cold air intake options for your BRZ and highlight our absolute favorites.

When Should You Upgrade to a CAI?

If you’ve modified cars in the past, you probably know that your engine wants clean air. Cold air? Even better! It’s a simple equation — cooler air means more horsepower.

Cold air has more oxygen molecules than warm air, and oxygen-rich air allows your engine to burn fuel more completely, and therefore more efficiently. So it’s no surprise that one of the cheapest and easiest ways to boost your BRZ’s performance is with an aftermarket cold air intake (CAI).

Subaru’s stock intake system is restrictive, so it limits the potential performance of your BRZ. This is because manufacturers are in a tussle between giving you high performance with a good airflow system while adhering to strict emission standards.

When you install a cold air intake, you move the air filter further out from the engine compartment, away from the heat. This allows cooler air to flow into the engine for better combustion.

Assuming you’ve already done a few mods and you’re looking to squeeze out some more from your BRZ, a cold air intake will do the trick. Not only can it improve power output and throttle response, but more excitingly, you’ll hear a nice change in intake noise too.

Supporting Mods & Upgrades

Depending on what you’re looking for, different air intake systems serve different purposes. An obvious reason to purchase a replacement would be due to wear and tear. That aside, CAIs usually come into the picture for heightened performance and sound.

Either way, before we get into the top options for upgrading your the intake on your BRZ, let’s look at a few supporting modifications and add-ons for you to look out for.

Heat Shield

The whole point is to control and reduce the temperature of the air going into your engine. This is doubly important if you live in a warmer climate where your intake alone won’t be enough to suck in cold air.

Heat shields have one or more layers of stamped metal designed to wrap around various parts of your exhaust system. The main goal is to reduce the heat around the filter area.

While your OEM heat shield will last you the life of your Subaru, if you’re aiming for more power, you may want to upgrade to a more heat-resistant material. Aluminum is the most popular option.

Intake Manifold

Sitting proudly on top of the engine, the intake manifold is integral to the combustion process. It maintains harmony between air mixed fuel, the spark, and the final combustion. A manifold features a series of tubes that ensure the even distribution of incoming air into all the cylinders.

The intake manifold also helps in cooling down the cylinders and preventing your engine from heating up. Using aftermarket performance manifolds with taller and larger runners feeds the engine more air and fuel to increase the torque, increasing horsepower as a result.

If you’re upgrading your CAI for power, then upgrading your intake manifold makes sense.

High-Flow Fuel Injectors

Fuel injectors spray fuel into your engine through an atomizing nozzle that evenly distributes fuel for optimum performance. Even though the OEM injectors get the job done, if you are looking to squeeze the most power out of your engine, then performance injectors will only help.

Especially with upgrades like a cold air intake, an aftermarket camshaft, or even changing engine displacement, your BRZ will be taking in more air, and so you will need to upgrade your fuel delivery system too.

Performance fuel injectors give you greater horsepower and torque, and if they are correctly tuned, they can also improve fuel economy.

Aftermarket Throttle Body

The throttle body sits between the air intake system and the engine manifold. It is integral to combustion engines as it controls the amount of air flowing into the engine.

Aftermarket throttle bodies are usually larger than stock parts. Not only do they boost overall horsepower, but they also increase acceleration performance.

If you’re looking for more torque, then you should consider upgrading your throttle body too.
