Koyorad Racing Hoge Druk 1.3 bar Radiateurdop large Type A (Universeel)

Pressurize your cooling system with the Koyo radiator cap. What sets it apart? It raises the pressure over the stock setup, which also raises the boiling point of the coolant. Doing so will keep your car running safer with more room for error, avoiding air pockets.

Can you handle the pressure? The Koyorad hyper Radiator Cap is for intelligent tuners who demand to extract every ounce of cooling efficiency from their performance machines. Koyorad highly recommends the 1.3 bar Koyorad Hyper Cap (Koyo part number SK-C13 or D13) for use with Koyorad All Aluminum Racing Radiators (when applicable). The Koyorad Hyper Cap is made in Japan with the highest quality components ensuring the best possible performance from your Koyorad Racing radiator. By increasing the coolant pressure and raising its boiling point, the faster your engine is relieved of excessive engine heat. The Hyper Radiator Cap withstands an open valve pressure rating of 1.3kg cm2, adding to under your the hood desire for extra toughness an elegant touch of style.

Each KoyoRad  radiator does NOT have a radiator cap at KoyoRad, so it has to get ordered seperately.

Please make sure that the right size is being ordered. You can confirm the size in picture 2.
