Race Flo / Race Master Intake Valves - Manley Performance Set of 8
The Race Master and Pro Flo versions, 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 below. Generally, higher engine speeds require titanium valves. Engine builders who have been successfully using EV-8 alloy (21-4N) valves will find that this series of Manley valves is an excellent product at a very attractive price. The ultimate tensile strength tables on this and the following pages demonstrate that the Manley Race series is equal to the best offered by our 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Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether or not these products can be installed on Japanese domestic 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 it up for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer name, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese market models without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. Shipping cost estimates are automatically calculated 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 cost. In such cases, we will contact you individually by email.
In principle, 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 yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are not shipped by sea freight.
○ Regarding Compatibility with Japanese Vehicle Inspection (Shaken)
In principle, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," 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 property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of your order. Since all products are shipped internationally from outside Japan, there may be damage to the packaging box or the product during shipping. We only accept returns, refunds, or exchanges for products with shipping damage, defective products, or items different from what was ordered if contacted within 7 days of receipt. Please understand that for products sold through our company, warranty support will be handled "only through our company." Please note that we do not handle support through other companies or distributors located in Japan.
