Maruha 18.5 psi Radiator Cap for Mazda MX-5 NA NB
Maruha’s heavy-duty radiator cap increases the pressure in the cooling system and uses superior materials to the OEM cap. Increasing the pressure of a cooling system allows you to increase the internal coolant temperature which causes heat to dissipate faster, increasing cooling efficiency. The cap also features a silicone seal as opposed to the OEM rubber seal, ensuring a longer life span and increased temperature resistance.
