HPS Red high-temperature 3-ply reinforced silicone coolant hose kit (15-piece complete set, Part Number 57-1815-RED) is a replacement for 2006-2007 Subaru Impreza WRX STi 2.5L Turbo, including stock OEM rubber upper and lower radiator hoses, heater hoses, and premium-grade high-heat-resistant auxiliary hoses made of materials that meet or exceed OE specifications (max temperature rating: 350°F). Compared to universal hoses found at local auto parts stores, the HPS silicone radiator and heater hose kit includes all the correct bends and curves for a perfect fit. The 100% stainless steel, non-perforated embossed hose clamps are easy to install, will not cut the silicone hose, and help prevent and resolve coolant leaks and engine overheating issues that can be caused by cracked, damaged, or collapsed OEM rubber coolant hoses. HPS silicone hoses perform well under extreme ambient and radiant temperature conditions and can withstand the harsh high-temperature and high-pressure operating conditions of an engine, maintaining peak efficiency during daily driving or racing competition. The HPS silicone hose kit comes with a limited lifetime warranty from HPS Performance Products.
Before You Order
〇 About Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
As our product database is primarily based on North American vehicles (USDM), please confirm whether the product can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model on our top page tabs, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product information is translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Delivery
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, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a rush, please inquire about lead times beforehand. Note that all items are transported via air freight. They are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Products we carry are generally designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection (Shaken) system," and we cannot provide strength evaluation documents or similar paperwork for the purpose of Japanese vehicle inspection. Therefore, all parts are sold for "circuit, private property, or off-road use only," and any installation or use is at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, packaging boxes or the items themselves may sustain damage during transit. Please understand that we will only provide returns, refunds, or replacements for items with shipping damage, defects, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
