DENSO 234-4787 OE-Identical Heated Oxygen Sensor 4-Wire Direct Fit 26.77" Wire

The DENSO 234-4787 is an OE-identical, direct-fit heated oxygen sensor engineered to deliver factory-level accuracy and reliability. Built by one of the world's largest original equipment manufacturers, this downstream O2 sensor is precision-manufactured to meet or exceed the same strict standards as the sensor originally installed on the vehicle.

Key Features:

• 4-Wire Heated Design: Integrated heater element brings the sensor up to operating temperature faster, improving emissions control and fuel efficiency from cold starts
• 26.77" Wire Harness Length: Pre-cut pigtail provides the correct reach for a clean, direct-fit installation with no splicing required
• Aluminum-Oxide Trap Layer: DENSO's exclusive protective coating shields the ceramic sensing element from silicone and lead contamination, extending sensor life and protecting the platinum electrode
• Double Protection Cover: Maintains optimal operating temperature for quicker response times while guarding the ceramic element against exhaust contamination
• 100% Quality Tested: Every sensor is verified for high-temperature signal output, air tightness, electrical continuity, and heat resistance before leaving the factory
• OE-Identical Construction: Matches factory wiring, connector type, and thread specification for a first-time, no-hassle fit

As a Tier 1 OE supplier to the world's leading automakers, DENSO brings unmatched manufacturing expertise to its aftermarket line. The 234-4787 restores accurate air-to-fuel ratio feedback to the engine control unit, helping optimize combustion efficiency, reduce emissions, and eliminate oxygen sensor-related trouble codes.
