The APR Brake Cooling Ducts are aerodynamically-optimized to "funnel in" massive amounts of air. Also known as the venturi effect, when the vehicle speed increases, this funneled-in air increases in both pressure and velocity as it passes from the larger frontal area into the smaller pipe section of the brake duct. When matched with appropriate high-temperature air duct hoses, the APR Brake Cooling Ducts will help to channel in large volumes of fresh air to help cool down red-hot brake rotors lap after lap on the track.

Excessive heat can cause major and expensive damage to critical components in a car. Engine bays, radiators, brakes, transmissions, and differentials all need good air flow to help transfer away unwanted heat. APR Air Ducts help bring fresh cooling air to different areas that need additional cooling. Built using pre-preg. carbon fiber reinforced polymer (CFRP) composite materials for superior strength-to-weight ratio, APR Air Ducts add both function and "lightness" where it counts.


  • Carbon Fiber Construction
    This component is formed in the autoclave at high temperatures using pre-pregnated carbon fiber manufacturing processes, for high strength and low weight.
  • UV Resistant Coating
    Each Air Duct is finished with UV-resistant clear-coat paint for resistance against various environmental conditions (take care of this as you would take care of your vehicle's paint finish - polish then coat with good-quality wax or synthetic protectant).

These really work

The installation was a bit tricky, but the instructions were very helpful. A few deviations I did make:
- On my 2018 STI, I did not cut any part of the crumple zone structure, the hose routed under the windshield washer reservoir and everything reinstalled.
- I also used a 3.5" hole saw everywhere, but the hole placement in the directions is pretty much spot on and everything lined up nicely.
- I highly recommend that you take the extra few minutes to check fitment actually bolting the caliper in place as the clearance between the backing plate and the caliper is very close. It may save you some frustration down the road.
- I also had to run down to my local hardware store and get a longer bolt for one of the holes, but that cost $2 and I was going there anyway for some other parts.
In all, very happy with the benefit these generate and I can't complain about the look either!!
