Advanced Oxygen Lambda Sensor | Emission Control & Engine Protection
Restore your vehicle’s optimal air-fuel ratio with industrial-grade O2 sensors engineered for performance longevity and precise exhaust monitoring.

Key Benefits:
Enhanced Fuel Economy: Stabilizes trim levels (FTLV) to prevent rich/lean conditions by ±0.1λ accuracy
Emission Compliance: Reduces hydrocarbon (HC) & CO output by 37% (per SAE J1979 testing)
Durable Construction: Crush-resistant stainless body + waterproof Deutsch connector

Technical Specifications:
◼ Sensing Element: Triple-layer ZrO₂ zirconia w/platinum electrodes
◼ Thread Size: M18x1.5 ISO standard (7/8”-24 UNF alternative)
◼ Connector Type: 4-wire heated circuit (2 white/1 black/1 gray)
◼ Temperature Range: -40°C to 950°C (-40°F to 1,742°F)

Installation Compatibility:
• Fits sedans with 2005-2018 model year inline-4/6 engines (Euro emissions spec)
• Output compatible with torque-based ECU strategies

Compliance Notes:
⚠️ Not for OBD-II exempt vehicles
⚠️ Non-CARB compliant for use in California
⚠️ Verify flange orientation & wire length match original equipment

“Compatibility determined ONLY by thread size (M18x1.5), wire count (4), & connector type – Not vehicle-specific”
