Breathe life into your engine – the top air intake systems every JDM enthusiast should know about.
When it comes to unlocking hidden horsepower in your JDM (Japanese Domestic Market) car, one of the easiest and most effective upgrades is a performance air intake system. By allowing more air to flow freely into your engine, these intakes improve throttle response, sound, and often fuel efficiency too.
Let’s dive into the best air intakes for JDM legends like the Nissan GT-R, Honda Civic, Subaru WRX, Toyota Supra, and more.
What Does a Performance Air Intake Do?
Before we jump into the list, here’s a quick breakdown:
A performance air intake:
Pulls in cooler, denser air
Improves combustion = more power
Increases throttle response
Often adds a sporty engine sound
There are two main types:
Cold Air Intakes (CAI): Bring in cooler air from outside the engine bay
Short Ram Intakes (SRI): Shorter path, louder sound, easier install
Now, let’s check out the top performers for JDM cars.
