PIII GR Corolla Airbox Intake Kit
The PIII GR Corolla Airbox Intake Kit is a complete OEM+ intake solution developed to increase airflow, improve induction sound and support higher engine performance while retaining the practicality of the original Toyota panel filter format.
After more than 12 months of development and real-world testing across multiple vehicles, from Europe imports to North America, we created an airbox that improves the GR Corolla’s intake path without compromising serviceability, fitment or OEM-style integration.
Unlike many open-cone intake systems, the PIII Airbox uses a sealed cold-air design, feeding the filter directly from the front of the car. The result is a cleaner, more controlled airflow path, improved pressure recovery at speed, and a more stable intake environment for both OEM and tuned cars.

Designed around the OEM panel filter format
The PIII GR Corolla Airbox has been engineered around the OEM Toyota panel filter format.
This allows the car to retain simple, reliable and affordable filter servicing, while also giving owners the option to upgrade to the included higher-flow panel filter for additional performance.
When paired with our PIII panel filter, our testing has shown gains of over +6 bhp compared with the stock airbox on OEM ECU settings, with further improvements across the power band on Stage 1 and Stage 2 EcuTek engine software.
As with any intake system, final gains depend on the vehicle specification, ECU calibration, supporting modifications, ambient conditions and total engine output, so you can safely expect from +6 bhp to + >20 bhp, depending on your state of tune.
Clean airflow, not just more noise
The goal of this airbox was not simply to make the car louder.
The PIII GR Corolla Airbox completely redesigns the intake path, making use of the available packaging space to create a sealed, unobstructed cold-air route from the front of the vehicle to the filter.
The incoming air is guided toward the panel filter in a controlled and direct way, helping maintain stable airflow before the MAF sensor and turbo inlet.
This is one of the main advantages of a properly designed panel-filter airbox. Compared with many cone-filter layouts, the panel filter format allows the airflow to approach the filter face more evenly, instead of reaching it from an uncontrolled angle inside the engine bay.
There is a reason why many high-level motorsport intake systems use large panel filter airboxes when packaging allows it: they offer excellent filtration area, contr
