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 8000 rpm or below. Generally, titanium valves are required for higher engine speeds. Engine builders already successfully using 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 demonstrate that the Manley Race series is equal to the best offered by the competition.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya 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 all product databases are based on North American vehicles (USDM), please confirm compatibility with Japanese 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 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 a product is sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean that it 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 payment. Estimates for shipping costs are calculated automatically 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with plenty of time. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported by air freight. 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 note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for 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 box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or products that differ from your order if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
