This high performance lubricant is designed to deliver maximum power output on NISSAN and NISMO supercharged engines with high power and very high torque output even when fitted with NOS (Nitrous Oxide System)

Traditionally boost is tapped by spacing out the factory T-MAP sensor on top of the intake manifold

case hardened piston rod which provides exceptional tensile strength and resistance to sand blasting and rock chipping

AEM Electronics Digital Boost Gauge -3050psi (30-4408) 1553 then the Sound Kit isAEM's Digital Boost Display Gauges combine unsurpassed accuracy, speed and control with an easy to read digital LED interface that displays boost in 1 PSI increments, and a sweeping LED "needle" that lines the edge and moves as boost from 0 to up to 50 PSI. The boost gauge's digital readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell. AEM's digital boost gauges include a 0 5v analog output
