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 is designed for use with compatible M18 x 1.5 oxygen sensor installations on modified exhaust systems.

The built-in filter element sits inside the adapter body between the oxygen sensor and the exhaust system. It weighs 40 grams and installs using compatible M18 x 1.5 threads 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: Houses an internal filter element inside the adapter body for use with compatible oxygen sensor installations.
  
  
• 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.
  
  
• COMPATIBLE WITH MODIFIED EXHAUST SYSTEMS: Designed for use with compatible M18 x 1.5 oxygen sensor installations on modified exhaust systems.
  
  
• 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.
