This adjustable pressure switch triggers a Stage 1 water-methanol system, a secondary pump, or another 12V accessory once boost crosses a set point between 1 and 15 psi, which makes it well suited to low-boost, positive-displacement supercharger and drag-race applications that need a simple on/off trigger rather than a mapped controller.

Snow Performance 81014 Features:

• Adjustable activation range of 1-15 psi
• Recommended for drag race and positive-displacement supercharged applications
• Can trigger a second fuel pump when paired with a Snow Performance relay module (SNF-20003)
