The HPS black high-temperature 3-ply reinforced silicone engine oil cooler coolant hose kit (part number 57-1748-BLK) replaces the hard-to-find, rare stock OEM rubber engine oil cooler hoses for the 2003-2007 Infiniti G35 3.5L V6. The VQ35DE RWD uses premium-grade, high-heat-resistant material that meets or exceeds OE specifications (maximum temperature rating: 350°F). Compatible with OEM part numbers: 21306-AM606, 21306-AM600, 21306-AQ811. Compared to universal hoses from local auto parts stores, the HPS silicone engine oil cooler hose kit features proper bends and curves for a perfect fit. The HPS silicone coolant hose kit includes 100% stainless steel non-perforated embossed hose clamps for easy installation without cutting the silicone hose. HPS silicone hoses prevent and resolve coolant leaks and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses. With excellent resistance to 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 and racing competition. The HPS silicone hose kit comes with a limited warranty from HPS Performance Products.
Before You Order
〇Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Checking Compatibility
All product databases are based on North American vehicles (USDM), so please check the compatibility for Japanese vehicles (JDM) before placing an order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not guarantee that 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 payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may rarely differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air; they are never shipped by sea freight.
○Regarding Japanese Vehicle Inspection Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar items for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," so please install and use them at your own risk.
○Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, the shipping box and the product may sustain damage during transit. We will only provide returns, refunds, or replacements for damaged products, defective goods, or items different from what you ordered if you contact us within 7 days of receipt. Please understand that for products sold through us, we will handle warranty-related issues "only through us." We do not provide support through other companies or distributors located within Japan.
