Description
The Mishimoto Radiator Hose Kit, part number MMHOSE-CTR-23BL, is a blue silicone upper and lower hose set engineered specifically for vehicles running the K20C1 engine. Built to replace the factory rubber hoses, this kit swaps in a precision-engineered silicone design while also giving the engine bay a cleaner, upgraded look. It’s a direct-fit, performance-grade cooling upgrade rather than a universal hose.
This Mishimoto cooling upgrade is constructed from four layers of silicone reinforced with heat-resistant embedded fibers, giving it a maximum temperature rating of 347F (175C) and improved pressure tolerance compared to the factory hoses. Durable worm gear clamps are included for a secure, reliable seal at every connection point, and the kit includes coolant overflow hoses in addition to the main upper and lower radiator hoses. Backed by the Mishimoto Lifetime Warranty, this specific version arrives in blue, with black and red also offered for those matching other engine bay accents.
Vehicle Applications
This hose kit is a specific, direct fit for the 2023-2026 Honda Civic Type R (chassis code FL5), which runs the K20C1 engine, and it also fits the 2024-2026 Acura Integra Type S (chassis code DE5), which shares the same K20C1 powerplant. Because fitment is specific rather than universal, this kit is designed to bolt into these two applications without modification.
