Mishimoto Oil Cooler Kit

2023–2024 Toyota GR Corolla 1.6L 3-Cylinder Turbo

MMOC-GRC-23NTSL

Overview:

The Mishimoto Oil Cooler Kit is engineered specifically for the 2023 and newer Toyota GR Corolla, a high-performance hatchback that blends everyday practicality with track-ready capability. Designed to address the elevated oil temperatures generated by the GR Corolla’s turbocharged 1.6L 3-cylinder engine, this kit provides reliable cooling to protect your engine during spirited driving or extended track sessions.

With the GR Corolla’s impressive output of 300 horsepower and a high 10.5:1 compression ratio, the engine oil experiences significant thermal stress, often exceeding 260°F under demanding conditions. Mishimoto’s oil cooler kit helps reduce these temperatures by an average of 13 degrees, enhancing engine longevity and maintaining optimal performance.

This complete kit includes a high-efficiency 14-row dual-pass bar-and-plate oil cooler, direct-fit mounting brackets, and premium braided stainless steel lines, making it an ideal upgrade for enthusiasts seeking improved oil temperature management without compromising daily drivability.

Construction & Design:

The oil cooler features a robust bar-and-plate design constructed from high-quality aluminum, ensuring excellent thermal conductivity and resistance to corrosion. The dual-pass configuration maximizes coolant flow through the cooler, enhancing heat transfer efficiency. The cooler is mounted in the upper grille area using precision-engineered brackets that provide a direct fit without requiring modifications to the vehicle’s bodywork.

The included oil lines are crafted from braided stainless steel with a protective black nylon sheath, combining strength, flexibility, and abrasion resistance. This construction ensures reliable oil flow under high pressure and temperature conditions while maintaining a clean, professional appearance under the hood.

The Mishimoto Oil Cooler Kit is designed for a straightforward installation on 2023–2024 Toyota GR Corolla models equipped with the 1.6L turbocharged engine. The kit includes all necessary hardware and pre-assembled oil lines to simplify the process. Installation involves mounting the cooler in the upper grille area using supplied brackets and connecting the oil lines to the oil filter sandwich plate.

No permanent modifications to the vehicle are required, and the kit is compatible with both street and track applications. Depending on your driving environment, you can choose between the thermostatic sandwich plate for regulated oil flow or the non-thermostatic version for maximum cooling efficiency in hot or track conditions.
