Description
The Mishimoto Performance Intercooler, MMINT-GRC-23SL, is a direct-fit forced induction upgrade engineered specifically for the 2023+ Toyota GR Corolla and its G16E-GTS 1.6L L3 engine. Finished in a durable silver powder coat, this intercooler swaps in a thick bar-and-plate core in place of the factory unit, giving the GR Corolla’s induction system real, measurable gains without a piecemeal approach.
Built around a 4″ thick bar-and-plate core with cast-aluminum end tanks and a CNC-machined inlet and outlet, this Mishimoto intercooler is designed to move more air, more efficiently, through the entire forced induction system. Compared to the stock intercooler, it offers a 52% increase in core volume and a 10% reduction in airflow restriction, which combine to drop intercooler outlet temperatures by 38.5°F. That cooler, denser charge air translates into bolt-on power gains of 11.42 horsepower and 14.93 ft-lbs of torque, making this a straightforward way to improve both performance induction and everyday cooling consistency. Anodized aluminum ducting directs airflow through the external fins for additional cooling efficiency, and the whole assembly is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This is a specific-fit forced induction component built for the Toyota GR Corolla, chassis code GZEA14, powered by the G16E-GTS 1.6L L3 engine. Coverage spans the GR Corolla Core trim from 2023–2025, the Circuit Edition from 2023–2024, the Morizo Edition for the 2023 model year, the Premium trim for 2024–2025, and the Premium Plus trim for 2025. Note that this intercooler is not designed to fit the 8-speed GR-DAT automatic transmission.
