Description

Eliminate Check Engine Light Issues After Exhaust Modifications

This O2 sensor spacer adapter features an integrated mini catalytic converter designed to resolve check engine light errors, such as P0420 codes, resulting from exhaust changes. Constructed from durable stainless steel, it threads between your exhaust pipe and oxygen sensor to maintain proper diagnostic readings. It provides an effective way to keep your vehicle running without persistent warning lights after modifying or removing a catalytic converter.

Features & Benefits

  • Integrated Mini Catalytic Converter: Contains an internal catalyst substrate to treat exhaust gases at the sensor tip, preventing catalytic converter diagnostic trouble codes.
  • Stainless Steel Construction: Resists rust, high temperatures, and corrosion in demanding underbody exhaust conditions.
  • Built-In Wire Mesh Filter: Blocks physical contaminants and debris while maintaining stable exhaust gas flow across the sensor.
  • Precision Threading: Features standard M18 x 1.5 male and female threads for a secure, leak-free connection to your factory sensor and exhaust bung.

Specifications

  • Material: Stainless steel with brushed metallic finish
  • Total Length: 46.8 mm
  • Base Width: 21.9 mm (hexagonal base)
  • Thread Standard: M18 x 1.5
  • Internal Threads: Female threads for sensor mounting
  • External Threads: Male threads for exhaust pipe installation
  • Design: Cylindrical stepped shape with integrated wire mesh filter and mini catalytic converter element
