These are Manley Performance’s ultimate design, featuring a fully sculpted "Pro Flo" underhead design to maximize airflow into and out of the cylinder. All Manley stainless steel valves feature double-chrome stems and hardened tips for long-lasting performance value. All Manley Subaru WRX and STi valves feature OEM-radius triple-keeper grooves for superior valve retention. Manley stainless steel exhaust valves are fully forged and machined from Inconel (yes, the same material used to machine turbine wheels for high-end turbochargers!) steel, providing superior hardness and heat resistance. Manley pays special attention to swirl polishing, fully machined combustion faces on the valve heads, and undercutting the stems relative to head diameter to achieve an excellent balance of strength and maximum flow. Compatibility - Subaru 2002+ WRX EJ20 Subaru 2004+ WRX STi EJ2507


Before Ordering

〇 Regarding Import Consumption Tax
At Shaft-ya, we pay the import consumption tax incurred at the time of importation on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.

Checking Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify whether parts will fit Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If you place an order without confirming compatibility, we cannot accept returns due to fitment issues.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model on the tabs on our top page, this does not necessarily guarantee that they will fit Japanese-model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.

○ Regarding Shipping
Shipping costs are paid at the time of settlement. Shipping estimates are automatically calculated on the checkout page once you enter your shipping address. 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.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international delivery takes approximately 7 to 14 days, so please allow plenty of time when placing your order. If you are in a hurry, please contact us in advance to confirm the estimated delivery time. Note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength inspection reports or similar documentation for this purpose. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use only," and any installation or use is at your own risk.

○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility that packaging or products may sustain damage during transit. Please understand that for damaged, defective, or incorrect items, we will only provide returns, refunds, or replacements if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or distributors located within Japan for these matters.
