Description
The Mishimoto MMAI-GRC-23 is a direct-fit performance air intake system engineered specifically for the 2023+ Toyota GR Corolla and its turbocharged G16E-GTS engine. On the dyno, this cold air intake proved gains of up to 4 horsepower and 4 ft-lbs of torque, and it’s built to deliver that extra pull without triggering check engine light codes.
As a purpose-built air intake system, this cold air intake replaces the restrictive factory setup with a design that boosts exiting flow rate by 42% and cuts airflow restriction by 10.5% under low-load conditions, sharpening throttle response and everyday drivability. The injection-molded MAF housing is precisely calibrated so the MAF sensor continues to read accurately, keeping fuel delivery and throttle mapping on target even after the upgrade. Under sustained high-load driving, the system helps maintain cooler intake air temperatures for more consistent performance, while the deeper, more aggressive intake tone under acceleration adds an extra layer of excitement to every pull through the gears. Whether you’re comparing this cold air intake filter to other cold air intakes on the market, this Mishimoto air intake pairs measurable flow and cooling gains with the sound most GR Corolla owners are after.
