Toyota GR Corolla (GZEA14L, 2023–present)

Like most aftermarket intakes for the GR Corolla, there is a possibility it may cause an error code regarding the pressure difference through the PCV. Tuning the car will remove this code from being an issue. We are working on a solution for those who are not planning on tuning.

Made to order in Brendale, Queensland. Ships Australia-wide. We confirm fitment and lead time with you after checkout — or ask first and we’ll come back to you.

What it is

Developed specifically for the Toyota GR Corolla, the Roccomotive Performance Intake System has been engineered to maximise cold air delivery while reducing airflow restrictions present in the factory intake system.

Using advanced 3D scanning and CAD design techniques, every component has been designed to integrate seamlessly within the factory engine bay while providing a significant increase in intake volume and airflow efficiency.

The system features a fully enclosed airbox housing a premium K&N high-flow air filter, helping isolate intake temperatures from engine bay heat while maintaining excellent filtration performance. A clear polycarbonate inspection cover allows the filter to remain visible while providing quick visual inspection without disassembly.

To complement the larger intake system, a custom powder-coated cooling panel is included to optimise airflow management and maintain a clean factory-like appearance.

Manufactured using advanced engineering-grade materials and supplied as a complete bolt-in package, the Roccomotive GR Corolla Performance Intake System has been designed for enthusiasts seeking improved airflow, premium aesthetics, and OEM-quality fitment.

Materials are stated per product. We don’t publish airflow, temperature or power figures — there is no test data behind them, so we describe what the part is made of and how it’s designed instead.

How it's built

Box, lid, pipe, gaskets, filter, hardware. Nothing you have to fabricate.

Made in Brendale

Scanned, designed and printed a few streets from where it’s fitted.

Every Roccomotive product starts as a 3D scan of the actual engine bay, is designed over that mesh by a mechanical engineer, and is printed here in the material chosen for its job. Metal parts — like the GR Corolla’s cooling panel — are laser cut and powder coated.

Questions

Asked before you ask.

Does this require tuning?
The intake system has been designed to operate with the factory ECU. Individual vehicle modifications may influence tuning requirements.
Is the factory airflow sensor retained?
Yes. The system retains factory sensor functionality.
Is the air filter serviceable?
Yes. The included K&N filter is washable and reusable.
Is installation reversible?
Yes. The system is a bolt-in design and can be removed if required.
Can this cause error codes?
Yes. Like most aftermarket intakes for the GR Corolla, there is a possibility it may cause an error code regarding the pressure difference through the PCV — we are working on a solution.
