Part Number: 15009-AK004

Description: Limited Edition Radiator Cap

Fitment: 08-14 Subaru WRX & STI

Details:

The HKS 1.1 Bar Limited Edition Radiator Cap has been designed to perform better and more efficiently when compared to an OEM radiator cap. This radiator cap is rated slightly higher than a stock pressured radiator cap which will hold more pressure, and allow the coolant to properly boil.

This will increase the cooling capacity of the coolant system, and makes for a great supplement for those who enjoy spirited driving, or the occasional weekend track event.
