Bosch Oxygen Sensor OE-Fit Single — Heated Direct-Fit with Stainless Steel Protection

BOSCH 13474 is a premium OE-fit oxygen sensor engineered for direct replacement to restore accurate air-fuel sensing and dependable exhaust performance.

This Bosch oxygen sensor draws on decades of sensor engineering to deliver a long-lasting, factory-grade replacement. Designed, tested and built to Bosch standards, the 13474 combines a corrosion-resistant stainless steel body, a fast-acting heater and true direct-fit connectors so installation is straightforward and performance is consistent with original equipment.

How does this sensor reach operating temperature quickly?

The BOSCH 13474 uses an integrated, fast-acting heater to bring the sensing element up to working temperature in seconds. Faster warm-up means the engine control unit receives reliable oxygen readings sooner after startup, improving combustion control during critical warm-up conditions.

• Built-in heater element for rapid activation
• Works with planar and 3-, 4-, and 5-wire thimble designs
• Helps stabilize fuel trims earlier after cold starts

What makes this sensor durable against exhaust conditions?

Bosch protects the sensing core with a double laser-welded stainless steel housing that is fully sealed and submersible. That robust construction shields the sensor from corrosive exhaust byproducts and road contaminants, extending service life compared with lesser-quality assemblies.

• Double laser-welded stainless steel body for corrosion resistance
• Submersible design prevents internal contamination
• Protective tube finishes indicate factory functional testing

Is the 13474 easy to install and fit my vehicle?

Yes — the Bosch 13474 is a true OE-fit part with factory-style connectors and pre-coated threads to simplify installation. It arrives ready to install, reducing the need for additional lubricants or wiring modifications when you verify compatibility with your vehicle.

• Direct-fit OE connectors and harnesses for plug-and-play replacement
• Threads pre-coated with anti-seize compound out of the box
• Confirm fitment using vehicle-specific fit charts for sensor position

Which vehicles is this sensor compatible with?

The BOSCH 13474 fits many GM vehicles from the mid-1990s through the early 2000s, including Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac models. Always verify exact engine and sensor position against your vehicle’s fitment guide to ensure correct application.

• Compatible models include select Buick (Century, LeSabre), Cadillac (DeVille, Eldorado), Chevrolet (Camaro, Silverado, Tahoe) and more
• Fitment varies by year, engine and sensor location—check fit checker before ordering
• Designed to match OE sensor connector types and wiring counts

Who is this for: The Bosch 13474 is aimed at DIY mechanics, professional technicians and fleet managers who need a reliable, OEM-quality oxygen sensor replacement that installs quickly and resists exhaust-related corrosion. Choose this sensor when you want Bosch-tested performance, a rapid heater response for better warm-up readings, and an OE-style fit to minimize installation hassle. Replace worn sensors at manufacturer-recommended intervals to help maintain engine performance, emissions control and fuel efficiency.
