Mishimoto Performance Aluminum Radiator — Honda Civic Type R FK8
The Mishimoto Performance Aluminum Radiator replaces the FK8's factory plastic-tank unit with a full-aluminum core that holds more coolant and rejects heat faster. Direct fit using OEM mounts — no fabrication required. The stock radiator is fine for a stock car driven sensibly. It's not fine for a tuned car, sustained track use, or hard driving in hot weather. Once coolant temps creep, the ECU pulls timing to protect the engine — which means you lose power exactly when you're asking the car to make it. The increased core volume and improved fin density of this radiator delay that pull-back significantly. 100% TIG-welded brazed aluminum construction with a 42mm-thick core (versus the OEM ~26mm). Includes the radiator, OEM-style mounting brackets, and required hardware. Pairs with the Mishimoto Intercooler for full cold-side coverage. Lifetime warranty.

Don't love your new purchase?
We'll take it back, no hassle.
To be eligible for a return, the item must be in the same condition you received it: unused, uninstalled, with all hardware, tags, and original packaging intact. Parts with install marks, cut wires, scratched hardware, or missing components are not eligible.
To start a return, contact us at marc@kodoautomotive.shop with your order ID, the part name, and the reason. We reply within 1–2 business days with an RMA number and the return address. Don't ship parts back without an RMA — unauthorized returns get refused at the warehouse.

All returns are subject to a 20% restocking fee to cover inventory, repackaging, and carrier handling. The fee is waived for defects, warranty claims, and wrong-item-shipped situations — those are on us.
Return shipping: You're responsible for paying your own shipping cost to return the item. Original outbound shipping is non-refundable. If the item value is over $75, we strongly recommend a trackable shipping service or purchasing shipping insurance — we can't guarantee that we will receive your returned item.
