1989-1990 Nissan 240SX Race Master Exhaust Valves - Set of 8 by Manley Performance
The Pro Flo versions, identified as Race Master and Race Flo valves, are manufactured from XH-426 material for exhaust and NK-842 material for intake. This series of valves is intended for bracket, drag, and oval track racers operating at 8000 rpm or less. Generally, titanium valves are required for higher engine speeds. Engine builders who have successfully used EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at a very attractive price. The ultimate tensile strength tables on this and the next page demonstrate that the Manley Race series is on par with the best offered by competitors.

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 there will be no additional charges beyond the total amount paid at checkout.
〇 Verification of Compatibility
All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using 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 checkout. 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 cost and 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 within 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 (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They do not comply 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 arrival. Since all products are shipped internationally from outside Japan, packaging boxes and products may sustain shipping damage. 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 products, or items different from your order. Additionally, for products sold through us, we will provide warranty-related support "only through us." Please note that we do not handle support through other companies or distributors located in Japan.
