The AEM No-Weld O2 Sensor Mount is the ultimate solution for adding an oxygen or wideband sensor to your exhaust system without the hassle, mess, and expense of traditional welding. Engineered specifically for 2.25-inch to 2.5-inch diameter exhaust pipes, this kit allows you to securely mount an O2 sensor quickly using common hand tools.

Crafted from high-grade, durable materials designed to withstand extreme exhaust temperatures and corrosive elements, the no-weld design creates a leak-free seal on mild steel or stainless steel exhaust systems. Whether you are tuning your vehicle on a dyno, installing an aftermarket air-fuel ratio gauge, or adding a secondary sensor, this mount provides a professional-grade installation in minutes.

Best Uses

1. Dyno Tuning & Diagnostics: Quickly add a wideband O2 sensor temporarily or permanently for air-fuel ratio monitoring during tuning sessions.
2. Aftermarket Gauge Installation: Perfect for integrating a performance AFR or lambda gauge without needing to remove the exhaust pipe and take it to a muffler shop.
3. Custom & Kit Exhaust Setups: Ideal for enthusiast project cars, off-road builds, and custom exhaust fabrication where a weld bung cannot be easily reached or welded.

Features

1. No-Weld Installation: Clamps securely onto the exhaust pipe without requiring a welder or specialized fabrication equipment.
2. Size Compatibility: Precision-engineered to fit exhaust pipe diameters ranging from 2.25 inches to 2.5 inches.
3. Standard O2 Threading: Features industry-standard M18 x 1.5 threads, making it fully compatible with most stock and aftermarket oxygen/wideband sensors.
4. High-Temperature Construction: Built with rugged, heat-resistant components to endure harsh under-car environments and extreme exhaust gas temperatures.
5. Leak-Free Seal: Designed to maintain a tight, secure grip that prevents exhaust leaks around the sensor port.

Benefits

1. Save Time & Money: Skip the trip to the exhaust shop and eliminate welding labor costs by installing it yourself in your garage.
2. Zero Pipe Removal: Installs directly onto the existing exhaust pipe underneath the vehicle using basic hand tools.
3. Reliable Data Accuracy: Provides a firm, stable mounting position ensuring your O2 sensor reads exhaust gases accurately.
4. Removable & Versatile: Can be easily uninstalled or relocated if you change your exhaust configuration or tuning setup.
5. Prevents Permanent Modification: Ideal for leased vehicles, temporary test setups, or pristine exhaust pipes where you prefer not to drill permanent holes or lay down weld beads.
