The Mugen F-Type fitment radiator cap aides in the efficiency of your vehicle's cooling system. The higher pressure in the radiator causes the coolant's boiling point to rise, thus increasing cooling efficiency. The open valve pressure is 1.3kg.cm2 compared to the normal/factory 1.1kg/cm2.

Vehicle applications: 88-91 Civic/CRX, 90-93 Integra, 92-01 Prelude, 90-05 NSX, and most aftermarket full aluminum radiators (Koyo/Fluidyne/CSF/etc)
