Feel's Honda TwinCam Radiator Cap 1.35kg/cm2 (Type F)
This radiator cap is a high-pressure type that increases the pressure inside the radiator, thus raising the coolant boiling point and increasing cooling efficiency. The open valve pressure is 1.3kg/cm2 compared to the normal 1.1kg/cm2 It demonstrates its power under high-load situations such as circuit driving.
Fits these car with the stock radiators: Honda Civic/CRX 88-91, Prelude 92-96, Integra 90-93, NSX NA1/NA2 91-2005. Will fit most after market radiators as well.
