Radiator Hose Kit Silicone for Honda Civic K20-K24 Swap, Reinforced Black and Yellow

Upgrade your K-series Honda swap with the PQY Silicone Radiator Hose Kit for K20-K24 Swap in Black & Yellow. This reinforced silicone hose kit is purpose-built to route the upper hose under your cold air intake, reducing unnecessary bends and clutter while boosting engine bay reliability and aesthetics. Designed for serious hobbyists and daily drivers alike, it helps maintain optimal coolant flow under demanding conditions, so you can push your K20/K24 swap with confidence.

Compatible with a range of popular builds, this kit is ideal for those upgrading or swapping in K-series engines:

• 1994-2001 Acura Integra w/ K-Series Swap Engine K20A2
• 1988-1991 Honda Civic/CRX w/ K-Series Swap Engine K20A2
• 1992-2000 Honda Civic w/ K-Series Swap Engine K20A2
• 1993-1997 Honda Del Sol w/ K-Series Swap Engine K20A2

For K24 swaps, the kit also works when using the K20 thermostat housing or the billet aluminum thermostat housing, making it a versatile choice for a variety of builds. The hose is made from multi-layer fiberglass reinforced silicone, delivering a smooth finish and durable performance under heat and pressure.

Key benefits include improved reliability and cleaner engine bays thanks to a more direct upper-hose routing, while the silicone construction resists heat, UV, and chemical exposure. The color combo—Black & Yellow—adds a subtle performance aesthetic that complements many aftermarket and OEM-style builds.
