Precision-engineered for universal exhaust bungs, this extender repositions the secondary downstream O2 sensor slightly out of the direct high-velocity exhaust flow, helping stabilize sensor readings on vehicles fitted with aftermarket downpipes, test pipes, or high-flow catalytic converters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandardized M18x1.5 Threading \u0026amp; Precision Dimensions:\u003c\/strong\u003e Features universal M18 x 1.5 male external threads and female internal threads to fit standard automotive oxygen sensors. Designed with an overall length of 45mm, a 22mm outer hex base for easy wrench tightening, a 16.5mm inner diameter recess, and an integrated 6mm inlet orifice to restrict direct exhaust gas contact without impeding sensor functionality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eECM Air-Fuel \u0026amp; Sensor Readout Stabilization:\u003c\/strong\u003e The engine control module (ECM) relies on O2 sensor signals to monitor residual oxygen levels and regulate stoichiometric air-fuel ratios (14.7:1). When installing high-flow downpipes or race headers, altered exhaust flow can trigger false sensor readings or check engine lights. This spacer backs the sensor out of the turbulent main stream, allowing the sensor to sample ambient exhaust gases cleanly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDurable CNC-Machined Heavy-Duty Build:\u003c\/strong\u003e Precision CNC-machined from high-strength steel with a polished silver protective finish to resist extreme exhaust heat, thermal shock, corrosion, and thread seizing.
