Oxygen Sensor Adapter with Internal Filter Element for M18 by 1.5 Thread

Stop Check Engine Lights After Exhaust Work with This Sensor Adapter

You finish your exhaust upgrade and that warning light pops right back on. You're stuck dealing with error codes every single drive, and the dashboard glow won't quit. This adapter helps you clear P0420 and P0430 codes after removing or modifying your exhaust system.

This adapter screws between your sensor and exhaust pipe using an M18 by 1.5 thread. The built-in filter element sits inside the adapter body and processes exhaust gases before they reach the sensor. It weighs 40 grams and installs without cutting, welding, or special equipment.

The body is made from SS304 stainless steel that resists rust and corrosion from heat and moisture. The internal filter element works with your sensor to provide more accurate readings. It fits most vehicles with M18 by 1.5 sensor threads and works on track cars or modified street builds.

The stainless construction handles high exhaust temperatures without warping or breaking down over time. The compact design keeps everything tucked close to your exhaust pipe without hanging low or catching on road debris. The threads match factory sensor specs and tighten securely without stripping or cross threading.

• STAINLESS STEEL BODY: Built from SS304 stainless steel that stands up to heat, moisture, and road salt without corroding or rusting through.
  
  
• INTERNAL FILTER ELEMENT: Processes exhaust gases inside the adapter before they reach your sensor, helping provide cleaner readings and fewer false codes.
  
  
• M18 BY 1.5 THREAD: Matches factory sensor threading on most vehicles, screwing in tight without needing adapters, reducers, or custom fittings.
  
  
• 40 GRAM WEIGHT: Stays light enough to avoid putting extra stress on your sensor threads while adding minimal weight to your exhaust setup.
  
  
• CLEARS P0420 AND P0430: Helps resolve common error codes that appear after removing or modifying your exhaust system, keeping your dash clear and clean.
  
  
• TRACK AND STREET USE: Works on modified vehicles used for racing, off-road driving, or daily street use where exhaust changes trigger warning lights.
  
  
• NO CUTTING OR WELDING: Threads directly onto your existing sensor bung without needing fabrication work, power tools, or permanent exhaust modifications.
