The HPS Black high-temperature 3-ply reinforced silicone coolant hose kit (15-piece complete set, Part No. 57-1814-BLK) replaces the stock OEM rubber upper and lower radiator hoses, heater hoses, and auxiliary hoses for the 2005 Subaru Impreza WRX STi. It uses premium-grade, high-heat-resistant materials that meet or exceed OE specifications (maximum temperature rating: 350°F). Compared to universal hoses from local auto parts stores, HPS silicone radiator and heater hose kits have all the correct bends and curves for a perfect fit and include 100% stainless steel, easy-to-install perforated embossed hose clamps that do not cut the silicone hoses, preventing coolant leaks and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses. Excellent for extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the harsh high-temperature and high-pressure operating conditions of the engine while maintaining peak efficiency during daily driving or racing competition. The HPS silicone hose kit comes with the HPS Performance Products Limited Lifetime Warranty.
Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Please note that our entire product database is based on North American vehicles (USDM). Before ordering, please confirm whether the product can be installed on Japanese market vehicles (JDM). (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please also note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, in rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation papers for the Japanese inspection system. Therefore, all parts are sold for the purpose of "circuit use, private land use, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or items different from your order. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through our company." Please note that we do not provide support through other companies or distributors located in Japan.
