1993-2001 Honda Prelude Race Master Exhaust Valves - Set of 8 by Manley Performance
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 8,000 rpm or below. Generally, engine speeds above that require titanium valves. Engine builders who have successfully used EV-8 alloy (21-4N) valves will find these Manley valves to be an excellent product at the most attractive price. The ultimate tensile strength charts on this and the following pages demonstrate that the Manley Race series is equal to the best offered by the competition.

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 beyond the total amount paid at checkout.
〇Compatibility Check
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing your order. (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 confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily mean they will fit 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 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 amount and the actual shipping cost. In such cases, we will contact you individually by email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within 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 dates. All products are transported via air freight. They are never shipped by sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products handled by our company are designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System (Shaken)," and we cannot provide strength evaluation documents or similar paperwork for the Japanese 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 immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be provided "only through our company." We do not provide support through other companies or distributors located in Japan.
