Fitment

  • 2015–2021 Subaru | WRX STI

Description

Here, you are looking at the HPS Performance hose kit for your 2015-2021 STI. This kit replaces all of the OEM coolant hoses. 

Key Features

  • The premium grade high-heat resistance reinforced silicone hoses are made with correct bends and curves to ensure a perfect fitment.
  • Replaces lower and upper rubber radiator coolant hoses.
  • Includes 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut thru the silicone hoses.
  • Prevent and fix coolant leaks and poor engine performance caused by cracked, damaged, and ruptured OEM rubber hoses.
  • Race proven engineered silicone hoses designed for prolonged high temperature service (Max. 350F).

Vehicle Application

2015-2021 Subaru STI 2.5L Turbo EJ25

Remark: Silicone hose water permeation rate is 10 to 15 times greater than standard EPDM rubber hose. Checking water level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.
