Mazda 3 Turbo Intake Cold Airbox

The CorkSport Advantage

Performance Advantage:

The CorkSport Cold Air Box uses two fresh air sources to feed the filter: the OEM fresh air duct and an additional opening to the fender well area. The airbox itself then blocks out the hot air produced by surrounding components in the engine bay. This lowers the inlet air temperature and results in the potential for additional performance!

Testing:

Testing of the CorkSport Air Box resulted in a sizable reduction in Intake Air Temperatures or IATs when compared to testing of the CS Short Ram Intake alone. Over the duration of the test, we found that the average IATs were 13 degrees colder with the Turbo Air Box installed. For the test, we focused on a long duration stop and then accelerated up to highway speeds to show what might happen during heavy traffic or when waiting for a long traffic light. The graph shows a widening gap between the SRI and SRI + Turbo Air Box as the time during the stop progresses. This is a result of the increase in IATs happening at a slower rate when the CS Turbo Air Box is installed, leading to a lower peak temperature once the stop is completed. This reduction in IATs can lead to additional performance when accelerating back up to speed.

OEM Fitment:

During the design process of the Intake Cold Air Box, maintaining the ease of installation was a top priority. The factory mounting locations have been retained along with the rubber isolators found in the OEM setup. This makes the installation straightforward and ensures that the CS Cold Air Box is allowed to move like the OEM system as needed during operation. The fresh air duct is also utilized to ensure that the best source of air is fed into the Mazda 3 Turbo Cold Air Box.

Serviceable Design:

Checking and servicing the air filter is made simple with direct access through the top of the Cold Air Box after removing the acrylic lid. It also allows for a peek at the filter for a great look in your engine bay!

Materials and Design:

Mazda 3 Turbo SRI Cold Air Box is made using a technique called Rotomolding and the specific material used is HDPE Plastic that has a thickness of 5mm or 0.190in. This material has been used on existing CorkSport parts such as the 2021+ Mazda 3 Turbo Inlet Pipe and has demonstrated great durability and resistance to the elements. For the access lid, transparent acrylic was selected to provide a view into the Cold Air Box so the filter and MAF housing could remain on display.

SRI + Cold Air Box Designed to Work Together:

Maximize the performance of the CorkSport Short Ram Intake by pairing it up with the Turbo Cold Air Box to help block out performance reducing hot air from surrounding engine bay components. The CS Cold Air Box takes advantage of the factory fresh air duct and air that enters from the fender area to provide the best source for the CS SRI.
