Description
The Mishimoto Oil Cooler Kit (MMOC-CTR-23TSL) is purpose-built for the 2023+ Honda Civic Type R and its high-revving 2.0L turbocharged engine, giving FL5 owners a direct-fit way to control oil temperatures during extended hard driving on street or track. At the heart of the kit is a 19-row stacked plate, bar-and-plate cooler that is positioned to receive maximum airflow, backed by a full line and mounting kit engineered specifically for this chassis.
Pushing a high-output engine hard for extended sessions can drive oil temperatures up, which is where this Mishimoto oil cooler kit earns its keep. By increasing total oil system capacity by 12% over stock and routing oil through a 19-row stacked plate cooler, the kit was shown in testing to run oil temperatures 5°F cooler than stock. The cooler is thermostatic, so it still allows oil to reach optimal operating temperature for everyday street driving while adding a meaningful buffer of cooling capacity for spirited or track use. As a piece of dedicated Mishimoto cooling hardware, it’s built to add confidence for drivers who want to push their Civic Type R harder and longer without worrying about oil breakdown from sustained heat.

Frequently Asked Questions
What vehicles does this Mishimoto oil cooler kit fit?
This kit is designed specifically for the 2023–2026 Honda Civic Type R (FL5).
How much does this kit reduce oil temperatures?
Testing showed oil temperatures running 5°F cooler than stock with this kit installed.
Does this kit increase oil capacity?
Yes, the kit increases total oil capacity by 12% over stock, in addition to using a 19-row stacked plate cooler positioned for maximum airflow.
Will installing this cooler affect the factory oil temperature display?
The FL5 Civic Type R does not have a factory oil temperature sensor, so the oil temperature reading shown on the vehicle display is an inferred value. Once this oil cooler is installed, that displayed value is no longer accurate.
What is included in the kit?
The kit includes one 19-row oil cooler, one bracket kit, one hardware kit, one oil line kit, one line separator, and one sandwich plate kit.
Is any trimming required for installation?
Yes, installation requires trimming or removal of the factory duct piece (71336-T20-A00); Mishimoto notes this trimming or removal will not affect performance.
