Description

Bosch 15586 oxygen sensor for the 2004-2010 Subaru Forester H4 2.5L and other vehicles measures the air-fuel ratio across the full lambda range. This upstream wide-band Bosch O2 sensor feeds the ECU continuous data, not a switching signal.

Fast light-off and optimized heater control, with ceramic construction for rapid load changes and thermal cycles
Built to withstand exhaust streams up to 1,880°F
Metal housing, integrated heater element and TSP coating to resist vibration, corrosion and contamination
Reaches operating temperature in under 7 seconds, so the ECU gets a signal quickly for closed-loop control
