Quiet Performance Where It Matters

Factory bypass valves are often built with lightweight plastic components and soft diaphragms that struggle under higher boost and heat. Over time, this can lead to boost leaks, inconsistent response, and reduced turbo efficiency.

The GFB T9302 is designed as a direct-fit recirculating bypass valve replacement that eliminates these weaknesses while maintaining factory-style operation and noise levels.

Built for Reliable Boost Control

Unlike spacer-based solutions that only alter sound, the T9302 replaces the complete valve mechanism with precision-engineered components designed to seal consistently under load. The result is dependable boost holding and smoother power delivery.

Key Benefits

• Improved boost holding under sustained load
• Sharper throttle response during partial throttle changes
• Faster boost recovery between gear shifts
• Fully recirculating design – no additional noise
• Durable construction suited to high heat and pressure

OEM-Friendly, Direct Fit Design

The T9302 is designed to install directly in place of the factory bypass valve with no permanent modifications required. It retains OEM-style operation while delivering a measurable improvement in response and reliability.

Designed for Long-Term Use

Manufactured using high-quality materials and engineered for harsh turbocharger environments, the GFB T9302 is built to withstand prolonged heat exposure and repeated boost cycles without degradation.
