SpeedFactory Racing 4 Bar MAP Sensor for K Series (1-43+PSI) center and the SpeedFactory Racing B-Series

and the SpeedFactory Racing B-Series VTEC Coil On Plug Adapter Plate is necessary for those making the switch

Upgraded valve springs are required

The SCHA base is TIG welded at multiple points where fatigue cracking and stock weld failure has been seen to create a much stronger assembly that offers more precise

You will save hours of tedious labor & frustration and retain the critical proper factory set backlash & gear mesh pattern

SpeedFactory Racing 4 Bar MAP Sensor for K Series (1-43+PSI) center and the SpeedFactory Racing B-SeriesSpeedFactory 4 Bar MAP (Manifold Absolute Pressure) sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip. Pressure changes are calculated on a true linear 0 5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows our MAP sensor to remain a minimum of 99% accurate from 32
