Tuspeed 4 Bar Map Sensor (WRX 06-07/STI 04-15)

These Tuspeed 4 bar MAP sensors are a drop in replacement for the factory parts yet will reliably cope with up to 4 bar boost pressure.

A true linear 0-5 volt output with inbuilt temperature compensation sensor means reliable operation across all boost pressures and at all altitude / weather conditions. Tuning becomes simpler, idle more consistent and drivability improved.

All sensors are pressure and function checked prior to leaving the manufacturer.
