AEM No-Weld O2 Sensor Mount for 2.75 to 3 inch Diameter Pipe

AEM No-Weld O2 Sensor Mount (2.75"–3" Pipes) | Easy Clamp-On Adapter

Easily install an oxygen sensor without welding! AEM's clamp-on O2 sensor mount fits 2.75" to 3" diameter exhaust pipes. Durable, leak-free, and quick to install.

The AEM No-Weld O2 Sensor Mount (2.75" to 3" Diameter Pipe) provides a fast, reliable, and hassle-free solution for installing an oxygen sensor into your vehicle’s exhaust system without the need for cutting or custom welding. Perfect for standard steel or stainless steel exhaust tubing, this clamp-on adapter creates an airtight seal around a drilled hole, allowing you to seamlessly integrate a Wideband UEGO sensor, air/fuel ratio gauge sensor, or replacement O2 bung.

Engineered with high-grade, corrosion-resistant stainless steel hardware and a heavy-duty sealing gasket, this mount is built to withstand extreme exhaust heat and continuous engine vibration. Whether you are setting up dynamic engine tuning, installing an aftermarket air/fuel ratio monitoring system, or simply adding a temporary sensor port for dyno testing, this kit saves significant installation time and eliminates expensive fabrication costs.

Best Uses

1. Aftermarket Wideband O2 Sensor Setup: Ideal for installing wideband UEGO sensor bungs when wiring up aftermarket air/fuel ratio (AFR) gauges.
2. DIY & Home Garage Engine Tuning: Perfect for enthusiasts and mechanics who do not own a welder or want a clean, non-permanent modification.
3. Dyno & Performance Testing: Excellent for temporary or quick-setup sensor placement during vehicle tuning and dyno runs.
4. Exhaust Upgrades: Compatible with standard 2.75-inch and 3-inch aftermarket or factory exhaust piping.

Features

1. No-Weld Clamp-On Design: Secures directly around the exhaust pipe using heavy-duty stainless steel band clamps, eliminating the need for specialized welding equipment.
2. Precise Pipe Fitment: Precision-engineered specifically to fit exhaust tubing diameters ranging from 2.75 inches to 3.00 inches.
3. High-Temp Sealing Gasket: Includes a specially formulated, heat-resistant gasket designed to prevent exhaust leaks and ensure accurate sensor readings.
4. Standard Sensor Threading: Machined with standard M18 x 1.5mm threads to accept almost all standard oxygen and wideband sensors.
5. Durable Stainless Steel Construction: Premium hardware designed to resist rust, corrosion, and severe exhaust thermal cycling.

Benefits

1. Saves Time & Money: Avoid expensive fabrication shop labor fees and lengthy installations—installs in minutes with basic hand tools.
2. Leak-Free Accuracy: The high-temperature seal ensures zero exhaust leaks, giving your wideband sensor precise air/fuel ratio data without false readings.
3. Non-Destructive Installation: Allows you to add an O2 sensor port without permanently modifying or damaging your exhaust pipe integrity with high heat welds.
4. Versatile & Reusable: Can be easily repositioned or removed if you change exhaust setups or need to transfer the unit to another vehicle.
5. Corrosion & Heat Resistance: Built to withstand harsh underbody environments, road salt, moisture, and high thermal strain.
