AEM No-Weld O2 Sensor Mount for 1.75 to 2.0 inch Diameter Pipe

AEM No-Weld O2 Sensor Mount for 1.75–2.0" Pipes | Part #30-2355-200

Install your wideband O2 sensor without welding! The AEM No-Weld O2 Sensor Mount (30-2355-200) fits 1.75" to 2.0" exhaust pipes for a quick, leak-free setup.

The AEM No-Weld O2 Sensor Mount (Part # 30-2355-200) provides a quick, reliable, and drill-only solution for installing an oxygen sensor or wideband UEGO sensor into your vehicle’s exhaust system. Eliminating the need for custom welding or visits to a fabrication shop, this heavy-duty mount allows you to install an O2 sensor bung in your garage using basic hand tools.

Engineered specifically to fit exhaust tubing with outer diameters ranging from 1.75 inches to 2.0 inches, this mount features a precision-machined, integrated bung welded to a stainless steel saddle clamp. The kit includes a high-temperature exhaust gasket and specialized high-temp sealing adhesive to ensure an airtight, leak-free seal under demanding engine temperatures and pressure. Whether you are installing an engine management monitoring kit, tuning a classic vehicle, or adding a wideband air/fuel ratio gauge, the AEM No-Weld Mount delivers professional results without the hassle of welding.

Best Uses

1. DIY Wideband Gauge Installation: Perfect for enthusiasts adding a wideband air/fuel ratio (AFR) gauge (such as the AEM UEGO) without access to TIG/MIG welding equipment.
2. Temporary or Diagnostic Tuning: Ideal for tuners who need to temporarily mount an additional oxygen sensor for dynamometer tuning sessions or track-day logging.
3. Exhaust Upgrades & Custom Fits: Excellent for custom, classic, motorcycle, or smaller-displacement vehicle exhaust systems with 1.75" to 2.0" outer diameter tubing.
4. Non-Weldable Piping: Great for vehicle owners working with exhaust pipes where standard welding is difficult or impractical.

Features

1. No-Weld Installation: Requires only a drill and basic hand tools to mount a standard O2 sensor directly to your exhaust.
2. Stainless Steel Construction: Built with durable stainless steel components to resist rust, corrosion, and high exhaust heat.
3. High-Temperature Gasket & Adhesive: Comes with a custom high-temp gasket and specialized adhesive to guarantee an airtight seal.
4. Integrated O2 Sensor Bung: Pre-fitted with a standard thread bung compatible with standard wideband and narrowband oxygen sensors (e.g., Bosch LSU 4.2 / 4.9).
5. Precision 1.75" to 2.0" Fitment: Custom-contoured saddle band engineered specifically for 1-3/4" to 2" outer diameter exhaust pipes.

Benefits

1. Saves Time and Money: Eliminates expensive fabrication shop labor costs and long wait times for custom welding work.
2. Leak-Free Performance: Dual-action sealing via the high-temp gasket and adhesive prevents exhaust gas leaks that could distort wideband readings.
3. Reversible & Reusable: Can be removed or relocated if you change your exhaust configuration or need to service the pipe.
4. Universal Vehicle Compatibility: Fits a wide range of automotive, motorsport, and custom exhaust setups as long as pipe diameter criteria are met.
5. Accurate Sensor Readings: Holds the oxygen sensor securely at the optimal angle and depth within the exhaust stream for precise air/fuel ratio telemetry.
