• Three‑pole configuration: Provides accurate voltage output for both pre‑catalytic converter (pre‑cat) and post‑catalytic converter (post‑cat) applications.
• Patented Bosch connector: Offers a secure, corrosion‑resistant interface that reduces wiring complexity and enhances signal integrity.
• Wide operating temperature range: Maintains performance from -40 °C to +125 °C, suitable for harsh engine bay environments.
• Compact, lightweight design: Facilitates easy integration into tight engine compartments without compromising durability.
• High‑accuracy sensor element: Delivers reliable oxygen readings essential for optimal fuel injection and emissions control.

Compatibility Overview

The 0258005726 lambda sensor is engineered to fit a broad spectrum of vehicles, including but not limited to:

• Nissan: Silvia (1994‑1999), Almera (2000‑2007), 300ZX Turbo Targa (1994‑1995), and many pre‑catalytic models.
• Subaru: Impreza (1993‑1998, 1994‑2000 turbo variants), SVX (1995‑1996), Legacy (1989‑2003), and other legacy engines.
• Renault: Clio Mk1 & Mk2, Kangoo, Scenic, and various pre‑cat models.
• Hyundai, Infiniti, Mazda, Ford, Buick, Chevrolet, and other OEMs across North America, Europe, and Asia.
• Engine types: 1.5‑3.0 L inline‑4, V6, and turbocharged configurations.

Because the sensor is designed for both pre‑cat and post‑cat positions, it can be used in vehicles that have undergone emissions system upgrades or those that retain original factory setups.

Installation Highlights

• The patented Bosch connector aligns with the vehicle’s existing harness, eliminating the need for custom adapters.
• Standard mounting brackets and threaded fittings are included, allowing straightforward bolt‑on installation.
• Wire routing is simplified due to the sensor’s compact form factor, reducing potential strain on the harness.
