2009-2018 Nissan GT-R R35

The COBB LF BPV is a compact, lightweight bypass valve engineered to deliver fast response and reliable boost control in tight engine bay environments. Designed with precision manufacturing and updated internal geometry, it provides improved sealing, quicker actuation, and simplified installation compared to traditional designs.

Emissions Compliance

This component is 50-state legal and approved for emissions-controlled vehicles.

• CARB EO Number: D-660-10
• Legal for sale and use in all 50 states when installed per manufacturer guidelines

Advanced Engineering

The LF BPV features a redesigned internal structure that reduces control volume by 30%, allowing for significantly faster venting of boost pressure. Combined with lightweight internal components, this results in quicker response and improved turbo system efficiency.

• High Boost Capability: Holds elevated boost levels without leakage
• Faster Response: Reduced internal volume and lighter components improve actuation speed
• Enhanced Durability: Larger piston O-ring increases sealing surface and reduces wear

Smart Design Features

• Banjo-Style Vacuum Port:
  • 360° adjustability for easier hose routing
  • Fewer potential leak points compared to traditional NPT fittings
• Improved Spring & Seal Design:
  • 60% increase in clamping force at peak boost
  • Maintains smooth operation during idle and transient conditions
  • Eliminates the need for manual spring preload adjustment

Key Benefits

• Reliable boost control under high-performance conditions
• Faster venting improves turbo response and drivability
• Compact design fits tight engine bays with ease
• Reduced maintenance with improved sealing and durability
