1994-2005 Mazda Miata Race Flo Intake Valves - Set of 8 by Manley Performance
The Pro Flo version, 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, higher engine speeds require titanium valves. Any engine builder who has successfully used EV-8 alloy (21-4N) valves will find these Manley series valves to be an excellent product at a most 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 any competitor.

Before Ordering
〇 Regarding Import Consumption Tax
At Shafutoya Shopping Site, we pay the import consumption tax incurred upon import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if the listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look it up 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 in the tabs on our homepage, 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 are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation sheets or similar documents for that purpose. Therefore, all parts are sold for use on "circuits, private land, and off-road" purposes, 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 is a possibility of shipping damage to the packaging or the product. We will handle returns, refunds, or exchanges only if contacted within 7 days of receipt for products with shipping damage, defective items, or items different from what was ordered. Please understand that for products sold through us, warranty-related support will be handled "only through us." We do not provide support through other companies or distributors located within Japan.
