as a boost gauge, water-meth controller and fuel system monitor all in one!

Proven to reduce the air inlet temperature by up to 100 degrees and increase octane by 25points for maximum HP and cooling .

Comes with adjustable Stage 3 water-meth controller, 4AN fittings, and stainless steel braided line to mount pump/tank in engine bay of vehicle.
