1988-1991 Honda CRX/Civic Race Master Exhaust Valves - Set of 8 by Manley Performance
The Race Master, and the Pro Flo version identified as 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, higher engine speeds require titanium valves. Any engine builder who has successfully used EV-8 alloy (21-4N) valves will find that this series of Manley valves is an excellent product at the most attractive price. The ultimate tensile strength tables on this and the following pages show that the Manley Race series is equal to the best offered by competitors.

Before You Order
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Confirmation of Compatibility
All product databases are based on North American vehicles (USDM vehicles), so please check the compatibility with Japanese vehicles (JDM vehicles) 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 check it for 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 using the tabs on our top page, this 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 cost 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 allow enough time when placing your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air freight. They are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products handled by our company are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar items for that purpose. 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. Since all products are shipped internationally from outside Japan, there may be damage to the packaging or the product due to shipping. Please understand that 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 regarding products sold through us, we will handle all warranty matters "exclusively through our company." We do not provide support through other companies or distributors located in Japan.
