WRX S4 VBH Prova Sports Radiator Cap C

Performance radiator cap with regulated valve pressure set to 127 kPa

A performance radiator cap that maximizes the performance of the cooling system.
By maintaining the internal pressure of the cooling system properly, cavitation of the entire system is suppressed and air bubbles are prevented from being generated in the cooling water, thereby stabilizing the cooling efficiency.
Stainless steel with excellent corrosion resistance is used for the cap body, and elastic heat-resistant silicon is used for the inner passage seal to improve the sealing performance, and higher durability and performance compared to genuine caps that are prone to deterioration. We have achieved both.
By keeping the error of the pressure valve spring within ± 0.1 kg / cm2, it is a high-precision and high-quality pressure cap as a replacement product.
