Description
The Speedhut 2-5/8″ 0-30 PSI Boost Gauge (L25-B4-LEG) is a vital instrument for any turbocharged or supercharged vehicle, providing accurate and real-time monitoring of manifold pressure. This gauge allows you to track both positive pressure (boost) generated by your forced induction system and negative pressure (vacuum) during engine idle and deceleration. Its 2 5/8-inch size offers excellent visibility while fitting comfortably in most gauge setups. Engineered for performance and reliability, this gauge comes complete with the necessary components for installation.
KEY FEATURES AND BENEFITS:
- Accurate Readings: Utilizes a 3-wire military-grade transducer, ensuring precise and responsive pressure measurements for optimal engine monitoring.
- Dual Functionality: Measures both boost (positive pressure) up to 30 PSI and vacuum (negative pressure), providing a comprehensive understanding of engine performance.
- Enhanced Visibility: Features LED backlighting (requires included harness) for clear viewing under various lighting conditions.
- Complete Kit: Ships with all essential components, including the pressure sensor, power and lighting harness, and pressure gauge wiring harness, simplifying the installation process.
- Standard Sizing: The 2 5/8-inch diameter and 2.68-inch hole size make it compatible with many standard gauge pods and mounting solutions.
- Reliable Performance: The military-grade transducer is designed for long-lasting and dependable operation.
