37mm Sport Compact Race Series™ Intake Valve - Single by Manley Performance
Manley Performance Sport Compact stainless steel valves utilize our superior "Race Series" alloy and are manufactured to the highest quality standards.
Manley valves are designed to survive in the most demanding environments and perform better than any other valve. Manley stainless valves feature gorgeous yet durable chrome stems, swirl polishing under the head, fully hardened tips, fully machined combustion faces, strictly controlled margin heights, and precise concentricity between stem and seat, resulting in an unmatched finished product.

Before placing your order
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
Our entire product database is based on North American market (USDM) vehicles, so please confirm whether the product can be installed on Japanese market (JDM) vehicles before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check 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 vehicle model in the tabs on our top page, this 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 once 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.
Essentially, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese vehicle inspection (Shaken) compliance
The products we handle are essentially all designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese vehicle inspection (Shaken) system" in any way, and we cannot provide strength calculation documents or similar paperwork for these inspections. 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. As 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 respond with returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or products that differ from your order. Furthermore, for products sold through us, we will only handle warranty-related matters "through our company." Please note that we do not handle matters through other companies or distributors located within Japan.
