Applications: EG, DC2 & EK (w/ EKK2 mounts only) with OEM or aftermarket RSX/EP3 Radiator and OEM K24/K20Z3 style, side mounted upper coolant neck. K-Tuned has added yet another custom rad hose kit for K-swapped vehicles. This set of upgraded hoses was designed to fit perfectly in a handful of K-swapped cars using the OEM RSX/EP3 radiator and most RSX/EP3 specific aftermarket units. Note that the RSX rad is a full width rad, so some simple modification and movement of the rad mounting tabs will be required for proper fitment on Civics. Also keep in mind that this hose set only fits with the OEM K24/K20Z3 style neck that mounts on the side of the cylinder head right above the transmission. K-Tuned rad hoses are made from strong, heat resistant, high grade, 4-ply reinforced silicone. The inner layers of silicone are red and the outer layer is finished in black with white K-Tuned logos at each end. These will fit with all PRB/ PRC, RBC/RRC and Skunk2 intake manifolds. No more installation headaches or messing around with universal hoses. Many other applications are available, including hoses for the RSX/EP3, 8th Gen Civic Si and K-Swap vehicles with half rad setups.
