Koyorad Performance Radiator - Honda Civic (EG6/EG9) / CR-X (EG2) - B16A MT
Koyorad has been building aluminium radiators for the performance and motorsport market for decades, and this unit brings that engineering to one of Honda's most loved chassis. The Honda Civic and CR-X B16A cars are prized for their rev-happy naturally aspirated character, and keeping coolant temperatures stable is essential whether you're running a stock engine or a built B16A pushing harder on track.
This listing covers manual transmission Honda Civic EG6 and EG9 models, along with the Honda CR-X EG2, from 1991 to 1995 (1992-1995 for CR-X).
