1993-2005 Lexus GS300 34.6mm Race Flo Intake Valve - Single by Manley Performance
The Pro Flo version, identified as Race Master and Race Flo valves, are manufactured with NK-842 material for intake and XH-426 material for exhaust. 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 demonstrate that the Manley Race series is equal to the best offered by the competition.

Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
All product databases are 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 investigate for you.)
If you 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 top page, it does not necessarily mean they will fit Japanese models 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, 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 delivery times. All products are transported via air freight. They will not be shipped by 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 documents or similar items for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," so please install and use them 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 or products. We will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding damaged products, defective products, or items different from your order. Please understand this. Furthermore, regarding products sold through us, we will provide warranty support "only through our company." Please note that we do not provide support through other companies or distributors located within Japan.
