Description
The Mishimoto Oil Cooler Kit (MPN: MMOC-CTR-23TBK) is a purpose-built cooling upgrade engineered specifically for the 2023+ Honda Civic Type R’s high-revving 2.0L turbocharged engine. At the heart of this kit is a robust 19-row stacked plate oil cooler positioned to receive maximum airflow, giving CTR owners a direct-fit way to manage oil temperature during hard driving. Independent testing showed the kit delivers oil temperatures 5°F cooler than stock, a meaningful improvement when the FL5 is pushed on track or during spirited street driving.
This Mishimoto oil cooler kit doesn’t just cool oil more effectively—it also increases total oil capacity by 12% over stock, expanding the system’s thermal buffer for extended hard-driving sessions. The cooler is thermostatic, so it still allows oil to reach optimal operating temperature for everyday driving rather than over-cooling. Black nylon oil lines with a billet oil line separator keep the plumbing organized and securely routed, while high-temperature silicone and fiberglass sleeves protect the stainless steel lines from heat and abrasion. As a complete cooling solution, this Mishimoto cooler kit combines performance, durability, and thoughtful engineering to give Type R drivers more confidence behind the wheel.

Frequently Asked Questions
What vehicles does this Mishimoto oil cooler kit fit?
This kit is a direct-fit for the 2023–2026 Honda Civic Type R.
How much does this kit reduce oil temperatures?
Testing showed the Mishimoto Oil Cooler Kit keeps oil temperatures 5°F cooler than stock.
Does this kit increase oil capacity?
Yes, the kit increases total oil capacity by 12% over stock.
Is installation difficult, and does it require trimming?
Installation requires trimming or removal of the factory duct piece (71336-T20-A00); trimming or removal of this piece will not affect performance. All direct-fit components are included, including black nylon oil lines, a billet oil line separator, and high-temperature silicone and fiberglass sleeves for the stainless steel lines.
Will the oil temperature gauge still be accurate after installing this cooler?
No. 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 and is no longer accurate once an oil cooler is added.
What is included in the kit and what warranty does it carry?
The kit includes a 19-row oil cooler, bracket kit, hardware kit, oil line kit, line separator, and sandwich plate kit, and it is backed by the Mishimoto Lifetime Warranty.
