2009-2014 Nissan GT-R Race Master Intake Valves - Set of 12 by Manley Performance
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 valve series is intended for bracket, drag, and oval track racers operating at 8000 rpm or less. Generally, engine speeds above 8000 rpm require titanium valves.
Engine builders who have successfully used 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 show that the Manley Race series is equal to the best offered by the competition.

Before Ordering
〇 Regarding Import Consumption Tax
At 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
As all product databases are based on North American vehicles (USDM), please verify 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 check for you.)
We cannot accept returns due to incompatibility if an order is placed without confirming compatibility beforehand.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily guarantee that 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 Delivery
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 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 via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic delivery within Japan, international delivery 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 the delivery date. All products are transported via air freight. They are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Essentially, all products we handle are designed and manufactured outside of Japan. Please note that they do not comply 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 damage to the packaging box or the product due to shipping. We will provide returns, refunds, or replacement exchanges only if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or products different from your order. Please understand that for products sold through us, we will handle warranty-related matters "exclusively through us." Please note that we do not handle matters through other companies or distributors located within Japan.
