DENSO 234-4792 Heated Oxygen Sensor Direct Fit Wire - 4-Wire 15.59

The DENSO 234-4792 is a direct-fit, heated oxygen sensor (O2 sensor / lambda sensor) engineered to OE specifications for precise monitoring of exhaust gases and air-fuel mixture balance. Built by one of the world's foremost original equipment manufacturers, this sensor delivers the same exacting quality found in factory-installed components.

Key Features:

• 4-Wire Heated Design — Integrated heater element brings the sensor up to operating temperature faster for more accurate readings under all driving conditions
• Direct Fit — Threaded mount with male connector and 15.59" wire harness length for a precise, no-modification installation
• Aluminum Oxide Trap Layer — DENSO's exclusive protection technology shields the ceramic sensing element from silicone and lead contamination, preserving platinum electrode integrity
• Double Protection Cover — Maintains optimal sensor temperature for quicker response times while guarding the ceramic element against contaminants
• Stainless Steel Housing — Corrosion-resistant construction for long-term durability in harsh underbody environments
• Porous PTFE Filter — Allows atmospheric oxygen into the sensor while blocking water and engine grime from entering the casing
• OE-Identical Standards — Manufactured and tested to strict OE tolerances for reliable emissions compliance and engine performance
