AEM 30-0309 X-Series 0-15 PSI Digital Boost/Fuel Pressure Gauge (52 mm)

Vehicle Fitment

• Universal -- works with any gas or forced-induction vehicle requiring 0-15 psi boost or fuel pressure monitoring

Fitment Notes

• Universal application -- not vehicle-specific.
• Requires connection to a pressure source and proper wiring for operation.
• Not recommended for use above 15 psi -- choose a higher-range gauge if needed.
• Emissions-legal in all 50 states -- does not affect vehicle emissions systems.

Features
