Product Description

Fits 1999-02 Silverado Sierra, 1994-97 Camaro Firebird, 1994-03 Corvette and many other 90s V8 GM Vehicles
This Upstream (front) Oxygen Sensor from Denso is the OEM-Identical replacement for your vehicle, providing the same accuracy and reliability your car or truck left the GM factory with. This 234-4012 part number fits most LS-powered vehicles with the flat 4-pin connector upstream oxygen sensor.
Features:
- Robotic Laser Weld - Ensures proper fit
- Porous PTFE Filter - Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing.
- Double Protection Cover - Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
- Stainless Steel Housing - Resists corrosion and contamination with a rugged, watertight body
- Aluminum-Oxide Trap Layer - Keeps silicone and lead outside the ceramic element through DENSO's exclusive design, preventing damage to the platinum electrode.
- OE Quality: Denso O2 sensors meet or exceed OE specifications, and in many cases are the OEM-supplied sensors from GM
Applications Include (Gasoline V8 Models, Upstream/Front Sensor):
Please verify your vehicle has the flat 4-pin style connector before ordering.
