Skunk2 4 Bar Map Sensor BRZ FRS 02-06 CR-V 02-06 RSX 02-11 Civic Si 04-08 TSX K Series

A 1 BAR MAP sensor reports barometric pressure times one, which is approximately 14.7 psi or 30in/Hg (inches of mercury). 2 BAR or 3 BAR simply mean two or three times above barometric pressure. The sensor will measure each direction, vacuum or pressure.

For Reference:
4 BAR will handle a forced induction up to 43.5 psi of boost

A vehicle's computer is calibrated to function at a specific level as programmed by the design engineer. A 4 BAR MAP sensor placed in a system designed for a 1 BAR sensor will not function correctly; in fact the system will run very rich because of the low return voltage signal. A computer that is programmable is a must for any tuner attempting to boost their engine's output with the addition of a turbocharger and a 4 BAR MAP sensor.

Skunk2 is proud to offer our very own 4 BAR MAP Sensor for the Subaru BRZ, Scion FRS, Toyota FT86 and the Honda K Series engines found in 2002-2011 Civic Si, 2002-2006 RSX, 2004-2008 TSX, 2003-2007 Accord, 2003-2011 Element, and 2002-2006 CRV.
