Nissan GT-R (R35) LF Bypass Valve by Cobb Tuning
The COBB LF BPV is a compact and lightweight bypass valve capable of holding extremely high boost pressures without leaking. Its updated design reduces control volume by 30%, allowing for extremely rapid boost venting during actuation. Innovative engineering and precision manufacturing have resulted in a compact package that fits within the tight confines of the engine bay.
Because the components are lightweight, the moving parts of the LF BPV have low inertia, allowing them to respond faster than the heavier components of other bypass valves. This latest design uses a banjo-fitting vacuum port that allows for 360 degrees of hose routing adjustment. This makes installation easier than NPT ports and reduces potential leak points.
This new design also includes a piston O-ring seal that is double the diameter of the older design, providing increased seal compression and reduced wear. The updated spring and seal design eliminates the need for spring seat adjustment while increasing clamping force at peak boost by 60%, all while maintaining similar behavior during idle and transient loads.

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 are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American specification vehicles (USDM), so please confirm whether the product can be installed on a Japanese specification vehicle (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look it up for you.)
If you place an 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 guarantee that they will fit Japanese model vehicles without modification.
All products are 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 quotes 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents or similar paperwork for these standards. 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 of your order immediately upon arrival. As all products are shipped internationally from outside of Japan, the packaging box or the product itself may suffer shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
