• Backed by the Mishimoto Lifetime Warranty for peace of mind

Construction & Design:

The Mishimoto Performance Intercooler features a heavy-duty bar-and-plate core measuring 4 inches thick, which is engineered to maximize heat dissipation and maintain lower intake air temperatures under demanding conditions. The core’s increased volume compared to the factory unit allows for greater air capacity and improved cooling efficiency.

Its end tanks are crafted from cast aluminum, providing exceptional durability and resistance to heat and pressure. The inlet and outlet ports are CNC-machined to ensure precise dimensions and smooth airflow, minimizing turbulence and pressure drop. The intercooler is finished with a choice of silver or black powder coating, offering corrosion resistance and a clean, aggressive look that complements the GR Corolla’s sporty styling.

The included anodized aluminum ducting is designed to channel air efficiently through the intercooler’s external fins, further enhancing thermal performance and maintaining consistent power delivery.

Performance & Sound

By significantly lowering the temperature of the intake charge, the Mishimoto Performance Intercooler improves combustion efficiency and reduces the risk of heat soak during extended spirited driving. This results in measurable power gains of over 11 horsepower and nearly 15 ft-lbs of torque, providing a noticeable improvement in acceleration and throttle response.

While the intercooler itself does not alter exhaust sound, the enhanced airflow and cooling support the turbocharger’s performance, contributing to a more responsive and engaging driving experience.

Installation & Fitment:

This intercooler is designed as a direct replacement for the stock unit on 2023–2025 Toyota GR Corolla models, requiring no cutting, welding, or permanent modifications. Installation is straightforward and can typically be completed with basic hand tools in a few hours. All mounting points align with factory locations, ensuring a secure and precise fit.

Because it maintains factory-style connections and dimensions, the Mishimoto intercooler integrates seamlessly with the vehicle’s existing intake and intercooler piping.
