Blow-off valve block-off kit for RB20/RB25 engines
Includes a plug to block the return hose port.
The kit features a black anodized finish. An O-ring is used for sealing, so no gasket is required.
Contents:

- O-ring
Fitment:
- RB20 (vehicles with factory J-pipe)

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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Checking Fitment
Our entire product database is based on North American vehicles (USDM), so please verify fitment for Japanese domestic vehicles (JDM) before placing your order. (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 look it up for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model on our homepage, it does not guarantee that they will fit Japanese model vehicles without modification.
All product descriptions are 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. In rare cases, there may be a significant difference between the automatically calculated shipping cost and the actual cost for large items such as body parts. In such cases, we will contact you individually via email.
Basically, 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 plenty of time for your order to arrive. 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. We do not ship by sea freight.
○ 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 "Japanese vehicle inspection standards," and we are unable to provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
