Vibrant Oxygen Sensor Bung

Vibrant Performance Oxygen Sensor Bungs: Precision Fittings for Serious Fabricators

When you're building a custom exhaust, routing a turbo downpipe, or relocating an O2 sensor on a modified engine, the quality of your sensor bung matters more than most builders realize. A poorly fitted or cheaply made bung can lead to exhaust leaks, inaccurate air-fuel readings, or even false check-engine lights that throw off a carefully tuned map. Vibrant Performance has spent decades earning its reputation as a go-to source for professional-grade fabrication hardware, and their oxygen sensor bungs are a prime example of why fabricators keep coming back.

A Style for Every Clearance Challenge

One of the most compelling things about Vibrant's sensor bung lineup is the variety of configurations designed to solve real-world fitment problems. Their catalog spans several distinct styles:

• Standard Weld Bungs — Vibrant Performance Standard Oxygen Sensor Weld Bungs are made of 304 Stainless Steel, Mild Steel, and Grade 5 Titanium , giving builders the flexibility to match the bung material to their exhaust pipe material for cleaner, stronger welds.
• J-Style Bungs — Vibrant Performance J-style oxygen sensor fittings help complete your project with quality bungs and great value; when clearance under the vehicle is an issue, their "J" shape allows for easier installation by placing the sensor parallel to the exhaust pipe.
• Saddle-Style Weld Bungs — Vibrant Performance Saddle Style Oxygen Sensor Weld Bungs are made of 304 Stainless Steel for optimum corrosion resistance, and feature a radius design which allows for a cleaner weld to tubing.
• 45-Degree Angled Bungs — Vibrant's 45° angled oxygen sensor bung is made from stainless steel with an M18 x 1.5 thread to fit all standard O2 sensors, with a convenient 45° angle for custom installs.

Built for the Demands of Performance Applications

Vibrant Performance Oxygen Sensor Fittings & Bungs are engineered to give fabricators, tuners, and performance enthusiasts the precision and durability they need when installing or relocating oxygen sensors — whether you're building a custom exhaust, adding wideband monitoring, or upgrading a turbo system. Crafted from high-quality stainless steel or aluminum, these fittings resist corrosion, extreme heat, and the demanding conditions of performance exhaust systems, and their precise machining ensures proper threading and a tight seal, helping prevent exhaust leaks that can cause inaccurate air-fuel readings or check-engine lights.

These oxygen sensor bungs come in a variety of sizes and configurations to support narrowband, wideband, and aftermarket tuning sensors — making them ideal for turbo kits, downpipes, custom headers, and high-flow exhaust systems — and their durability and precision help ensure your engine management system receives consistent data.

The standard M18 x 1.5 thread pitch used across Vibrant's bung range means they accept all standard O2 sensors , so there's no need to worry about compatibility whether you're running a factory narrowband unit or an aftermarket wideband controller. Vibrant Performance offers a large assortment of high-quality, easy-to-weld sensor fittings, bungs, and the accessories needed to complete your project.

The Vibrant Pedigree Behind Every Bung

Vibrant Performance has been designing, manufacturing, and delivering exhaust and induction components for the sport compact, hot rod, muscle car, truck and motorcycle markets since 1997, and is a division of Vibrant Power — a global leader in the design and production of exhaust and vibration control components for the automotive industry. That deep manufacturing heritage means even small components like sensor bungs benefit from the same engineering discipline applied to Vibrant's larger exhaust systems and turbo components. For builders who demand accuracy and longevity at every point in their exhaust system, Vibrant's oxygen sensor bung selection is a natural fit.
