Following the great success of the ISR V2 SR20DET manifold, the company has released the new Schedule 10 Weld-El bottom mount manifold. The version 3 manifold is an upgrade over almost every other bottom mount manifold. It uses thicker Schedule 10 Weld-El piping.
With all the OEM replacement manifolds on the market, choosing a manifold that will last can be a major issue. With this manifold, you can have peace of mind while upgrading to more horsepower. And, keeping ISR's high quality standards in mind, you know you are getting a superior product.
Note: For some T25 or T28 factory turbos, you may need to clock the turbo slightly to clear the manifold's larger runners.
Only legal for use on competition vehicles that are not registered or licensed and cannot be used on public roads or highways. It may also be used on other exempted vehicles.
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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All of our product databases are based on North American vehicles (USDM), so please check the compatibility with Japanese 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 be happy to check for you.)
If you order without checking 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, it 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 payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually by 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 order with enough time to spare. If you are in a hurry, please contact us in advance to confirm delivery dates. Please note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection Compatibility
The products we carry are generally all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system" in any way, and we cannot provide strength calculation documents or similar paperwork for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging boxes or products. Please understand that for products with shipping damage, defective products, or products different from your order, we will only handle returns, refunds, or replacement exchanges if you contact us within 7 days of receipt. Furthermore, for products sold through our company, we will handle all warranty-related matters "exclusively through our company." Please note that we do not handle matters through other companies or distributors located within Japan.
