Race Flo Intake Valves - Set of 8 by Manley Performance
Pro Flo versions, identified as Race Master and Race Flo valves, are manufactured using XH-426 material for exhaust and NK-842 material for intake applications. This series of valves is intended for bracket, drag, and oval track racers operating at 8000 rpm or below. Generally, engine speeds beyond this 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 a 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 any competitor.

Before You Order
○ Regarding Import Consumption Tax
At the 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.
○ Confirmation of Compatibility
As our entire product database is based on North American (USDM) vehicles, please confirm compatibility with Japanese (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 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 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. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs is automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may occasionally differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
Essentially, 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 plenty of 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. They will not be shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please be aware that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents 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, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
