Cobb Tuning WRX/STI 1300X² Fuel Injectors
Cobb Tuning is pleased to offer the 1300x² fuel injectors, designed in partnership with Injector Dynamics and Bosch Motorsport. This collaboration allows us to provide high-flow injectors with characteristics specifically tailored to the needs of motorsport tuners.
The Cobb Tuning 1300² was designed with alternative fuels in mind and is the only high-performance injector with all-stainless steel internal construction. It is compatible with all known fuels and resists alcohol corrosion better than any other injector on the market. While the Cobb Tuning 1300² was designed with ethanol-fueled engines in mind, it also accounts for the need to switch back to gasoline in certain situations. The Cobb Tuning 1300x² features a minimum fuel mass compatible with gasoline use, providing excellent idle and cruise operation under these conditions. In addition to being capable of handling multiple fuels, the Cobb Tuning 1300x²'s compact body makes it highly adaptable, making it one of the most versatile injectors available.

Before Ordering
〇 Regarding Import Consumption Tax
At 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 other than the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will check 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 using the tabs on our top page, it does not necessarily mean they are compatible with Japanese models 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 actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with plenty of time. If you are in a hurry, please contact us to confirm delivery times in advance. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Our products are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon receipt. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges if contacted within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
