When installing an aftermarket surge tank, removing, installing, and tightening the intake manifold bolts can be difficult, which is why we developed this high-quality stud kit.
Made from stainless steel, this kit looks great and offers excellent corrosion resistance.
It is designed exclusively for use with the following popular surge tanks frequently used on RB25/26 engines:
- Plazmaman
- Hypertune
Contents:
- 14 x Stainless steel studs
- 14 x Stainless steel smooth flange nuts
Note: Because the RB25 and RB26 cylinder heads have a different number of intake manifold bolt holes, this kit comes with 14 pieces so it can be used on either head.
Note: On some manifolds, weld thickness near the studs may vary, which may require the use of non-flanged nuts or nuts with a smaller profile.
Note: Not compatible with genuine or Trust surge tanks.
Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to assist 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 homepage, it does not necessarily 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 checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. We do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural study documents or similar certification for Japanese inspections. 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 of your order immediately upon arrival. Since 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 products if you contact us within 7 days of receipt regarding products with shipping damage, defective items, or incorrect items. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
