Oxygen Sensor Adapter with Integrated Mini Catalytic Element and Mesh Filter, M18 × 1.5

Keep Modified Exhausts Running Steady with This Sensor Adapter

You swap out your exhaust system and the check engine light keeps showing on your dash. You keep resetting codes each week, unsure if something is actually wrong or just reacting to changes. This adapter helps maintain steady sensor readings during track use, off-road driving, or custom builds where exhaust parts have been changed.

This adapter screws directly into your existing sensor port using M18 × 1.5 threading. The built-in mini catalytic element sits between exhaust flow and the sensor to balance readings. It regulates gases before they reach the sensor, helping reduce irregular feedback that can trigger codes like P0420 or P0430.

The body uses SS304 stainless steel that resists corrosion and heat exposure. A mesh filter inside helps protect the catalytic element from debris and contaminants. It weighs 0.088 pounds and installs without extra tools or wiring changes.

The compact design fits tight engine spaces where clearance around sensor ports is limited. The stainless threading handles repeated installation and removal during tuning sessions. This adapter is intended for track use and off-road builds where exhaust changes affect sensor readings.

• MINI CATALYTIC ELEMENT: Integrated converter balances exhaust flow before reaching the sensor, helping reduce irregular readings in modified systems during track use.
  
  
• SS304 STAINLESS STEEL BODY: Resists rust, corrosion, and heat exposure through repeated sessions, maintaining structure under demanding conditions.
  
  
• M18 × 1.5 THREADING: Fits most common sensor ports found in performance vehicles, screwing directly into place without extra hardware needed.
  
  
• MESH FILTER PROTECTION: Blocks debris and contaminants from reaching the catalytic element, extending lifespan during off-road driving conditions.
  
  
• TOOL-FREE INSTALLATION: Hand-tighten into the sensor port in minutes without special equipment, allowing quick setup between tuning sessions.
  
  
• LOW MASS BUILD: Weighs just 0.088 pounds, adding minimal weight while fitting into tight engine bays with limited space.
  
  
• TRACK AND OFF-ROAD USE: Intended for racing and off-road applications where exhaust changes require adjusted sensor feedback.
