DENSO 234-4933 Direct Fit 4-Wire Heated Oxygen Sensor 37.6" Wire

The DENSO 234-4933 is a direct-fit, heated oxygen sensor (O2 sensor) featuring a 4-wire design and a 37.6-inch wire lead. Engineered and manufactured to original equipment (OE) standards, this sensor delivers precise air-fuel ratio monitoring to help maintain optimal engine performance, maximize fuel efficiency, and minimize harmful exhaust emissions.

Key Features:

• Direct-Fit Design: Engineered as an exact OE replacement for a straightforward, first-time fit with no modifications required
• 4-Wire Heated Construction: Integrated heater element brings the sensor to operating temperature quickly, ensuring accurate readings immediately after cold starts
• 37.6-Inch Wire Lead: Generous wire length simplifies installation and routing in the engine bay
• Aluminum Oxide Trap Layer: DENSO's exclusive protective layer shields the ceramic sensing element from silicone and lead contamination, extending sensor life
• Stainless Steel Housing: Durable, damage-tolerant construction withstands extreme exhaust system temperatures and harsh operating conditions
• Porous PTFE Filter: Allows atmospheric oxygen to enter the sensor while blocking water, oil, and engine contaminants from entering the casing
• OE-Grade Quality: Manufactured and tested to strict OE specifications by DENSO, a globally recognized OE supplier to major automakers

DENSO oxygen sensors are part of the brand's First Time Fit® product line, meaning every unit is precision-built to meet or exceed original equipment standards right out of the box. Replacing a worn or faulty O2 sensor with this DENSO unit helps restore closed-loop fuel control, reduce harmful emissions, and protect your catalytic converter from damage caused by a rich-running engine.
