Product Description

The Mishimoto MMAI-GRC-23 is a direct-fit performance air intake engineered specifically for the 2023-2025 Toyota GR Corolla and its turbocharged 1.6L G16E-GTS engine. By replacing the restrictive stock airbox with a high-flow oiled filter and a precisely calibrated injection-molded MAF housing, this intake delivers dyno-proven gains of up to 4 horsepower and 4 ft-lbs of torque while increasing exiting airflow by 42%. The system also reduces airflow restriction by 10.5% under low-load conditions and keeps intake temperatures in check under hard driving - both critical for turbocharged applications.

Unlike many aftermarket intakes, the MMAI-GRC-23 is engineered to maintain full compatibility with the GR Corolla's sensitive PCV system and stock ECU tune, meaning no check engine lights and no retune required. Installation is straightforward with common hand tools, and the system is made in the USA and backed by Mishimoto's Lifetime Warranty. CARB compliant under EO# D-759-30, this intake is a clean, reliable upgrade for GR Corolla owners who want real performance gains without compromising daily drivability.
