Introducing the Turbo Mazda 3 Cold Air Box! Designed specifically to integrate alongside the existing CorkSport Skyactiv Turbo Short Ram Intake, and when combined, the complete intake system provides the best of both worlds. This includes both an intake that is less restrictive than OEM and Intake Air Temperatures that are colder to maximize performance potential.
Through the utilization of the OEM intake snorkel and an opening that accesses the driver fender area, it provides multiple sources of “cooler air” that the SRI can draw from that are away from engine bay heat to capture the coldest air available.
Below is a model of the Turbo Air Box assembly with the OEM snorkel that illustrates the locations that the air box draws from while blocking out the heat radiating from surrounding components like the radiator and engine.
Testing was an important part of the process as it shows to what degree the CS Turbo Cold Air Box is impacting IATs. The test was designed to represent what could occur if you were stopped for a long time during heavy traffic or when waiting for a long traffic light. After the stop, we then accelerated back up to highway speeds. The tests were conducted with an ambient temperature of roughly 45 degF so those of you that live in hotter climates will see elevated temperatures.
The start of the test begins with a 5 minute period where the car is stationary and from there we accelerated up to ~50mph. For the duration of the test, we observed that the addition of the CS Turbo Air Box netted average IATs that were 13 degrees colder than the SRI alone.
For the stationary section of the test, the graph shows that the gap in temperature between the SRI and SRI + Air Box continues to get wider as time progresses. This demonstrates the advantage of the Air Box and the lower rate at which the IATs increase when it is installed. Once the car takes off from the stop, the SRI + Air Box combo also returns to ambient temperature quicker, allowing the engine to take advantage of the colder ambient air sooner and help maximize power.
The material and construction of the CorkSport Air Box plays a role just as important as it performs so that it will last for many years to come. We kept the same manufacturing method and material that we used previously for the non-turbo Air Box, as it has been thoroughly tested and proven to excel in this application.
XDPE plastic makes up the main body of the Air Box and features properties that help it withstand chemicals and the elevated temperatures seen in the engine bay. Other CS parts that are located in the engine bay also utilize this same material, including the MASSIVE 4th GEN Mazda 3 Turbo Inlet Pipe.
Finishing off the top of the Air Box is the acrylic lid that is translucent with a grey tint to provide a convenient way to check on the condition of the air filter. The lid is removable and allows for servicing of the filter to be completed without the removal of the full Air Box assembly.
Rounding out the CorkSport Turbo Air Box is the inclusion of all necessary hardware and detailed instructions, allowing you to install the Air Box in as little as 30 minutes. Be sure to head over to the web page or reach out to the team if you have any questions and stay tuned throughout the coming year for more CS releases for your Mazda.
