Bosch 13652 Premium 3-Wire Heated Oxygen Sensor

The Bosch 13652 is a premium 3-wire heated oxygen sensor designed as a direct OE replacement for upstream (pre-catalytic converter) applications. Built on decades of oxygen sensor engineering — Bosch invented the automotive O2 sensor — this unit delivers accurate voltage signals to your vehicle's emission control computer for precise air-fuel ratio management and efficient combustion.

Key Features:

• Premium ceramic sensing element constructed with Zirconium or Titania and Yttrium for superior resistance to mechanical and thermal shock
• Patented catalytically activated fine particle filter prevents contamination and ensures precise voltage output to the engine's ECU
• Dual-filter protection — a second filter layer doubles defense against exhaust gas contamination, significantly extending sensor service life
• Heated design allows the sensor to reach operating temperature quickly for optimum performance across all driving conditions
• OE-style silicone boots provide a snug, secure fit with proper form and function
• Direct plug-in installation — no cutting or splicing required; true OE-connector fitment
• Helps protect the catalytic converter by preventing the premature failure caused by inaccurate fuel mixture readings
• Rigorously tested to meet Bosch's strict quality and performance standards

Specifications:

• Wire Configuration: 3-wire
• Wire Length: 14.4 inches
• Sensor Type: Heated
• Location: Before catalytic converter (upstream)
• Quantity: Sold individually
• Product Fit: OE replacement

The Bosch 13652 is sold individually and is engineered to restore factory-level emission control performance, improve fuel economy, and reduce harmful exhaust emissions — all with a hassle-free installation that requires no modifications.
