Mitsubishi EVO10 / Lancer Ralliart LF Bypass Valve by Cobb Tuning
The Cobb Tuning LF Bypass Valve is a compact, lightweight bypass valve capable of holding very high boost pressures without leaking. The modern design reduces control volume by 30%, allowing for extremely quick boost venting during actuation. Innovative engineering and precision manufacturing result in a compact package that fits within the confines of tight engine bays.
Due to the lighter weight of its components, the LF Bypass Valve's moving parts have low inertia, allowing them to respond faster than the heavier components of other bypass valves. This modern design utilizes a banjo fitting vacuum port that allows for 360-degree adjustment of the hose routing. This makes installation easier than NPT ports and results in fewer potential leak points.
This new design also incorporates a piston O-ring seal that is twice the diameter of older designs, providing enhanced seal compression and reduced wear. The updated spring and seal design eliminates the need for spring seat adjustments while increasing clamping force at peak boost by 60%, all while maintaining similar behavior during idle and transient loads.

Before Ordering
〇 About Import Consumption Tax
At Shaftoya 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
Our entire product database is based on North American (USDM) vehicles; therefore, please check compatibility with Japanese (JDM) vehicles before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by year, make, and model using 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. 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 checkout. Shipping estimates are automatically calculated 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 via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please order with ample time. If you are in a hurry, please contact us to check the lead time in advance. Please note that all products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please understand 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 the purpose of "circuit, private property, or off-road use," and any installation or use is 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 packing box or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
