Description
If you just purchased a Koyo radiator, maximize its performance with the Koyo’s 1.3 bar high-pressure radiator cap!
The Koyorad high pressure cap withstands an increased valve pressure rating of 1.3kgf/cm2 (1.3 bar) (18.9 psi) (130 kPa) which increases the boiling point of water and relieves high-performance engines of excessive heat.
This cap is highly recommended for use with every Koyorad all aluminum radiator (when applicable). The KoyoRad Hyper cap is crafted in Japan from high-quality materials to ensure longevity and performance from your KoyoRad Racing Radiator.
This cap is a deep plunger type and fits all Koyorad radiators with filler necks.
