The SSAutoChrome shorty 90 degree oxygen sensor spacer is designed to reposition compatible O2 sensors in tight exhaust installations without requiring cutting or welding when a suitable threaded mounting bung is already present.
A compact right-angle O2 sensor extension for custom exhaust fabrication, performance downpipes, racing headers and compatible M18 x 1.5 sensor installations.
Premium Features at a Glance
Changes the mounting direction of a compatible oxygen sensor.
Corrosion-resistant material for demanding exhaust environments.
For matching oxygen sensors and threaded exhaust bungs.
An angled option where straight extensions may be inconvenient.
Premium 304 Stainless Steel O2 Sensor Extension
When building a custom exhaust system, even a small clearance issue can create a major installation challenge. An oxygen sensor mounted directly into a downpipe, header or exhaust bung may interfere with nearby brackets, the vehicle floor, heat shielding or surrounding components.
The SSAutoChrome shorty 90 degree O2 sensor adapter offers a compact right-angle mounting option. Instead of using a straight oxygen sensor extender, this stainless steel fitting changes the direction of the sensor mounting point for more flexible positioning in compatible exhaust installations.
Manufactured from 304 stainless steel with a high-polish finish, the adapter is designed for builders who value material quality, corrosion resistance and clean exhaust-component presentation.
Whether you call it an O2 sensor spacer, oxygen sensor extension, lambda sensor elbow, exhaust bung adapter or M18x1.5 angled fitting, this component provides a practical threaded connection for appropriate custom applications.
Why Choose a Shorty 90 Degree Design?
Not every exhaust installation has room for a long, straight oxygen sensor extension. The shorty configuration is intended for applications where compact packaging and a change in sensor orientation are useful.
- Angled mounting: Repositions the sensor approximately 90 degrees from the original mounting axis.
- Compact layout: Offers an alternative to longer straight spacer configurations.
- Flexible positioning: Useful when checking clearance around fabricated downpipes and exhaust assemblies.
- Threaded installation: No welding is required when the exhaust already has a compatible M18 x 1.5 bung.
- Polished appearance: Clean finish suitable for performance exhaust assemblies.
Why 304 Stainless Steel Matters
Exhaust components are exposed to heat, moisture, road contamination and repeated thermal cycling. Material selection is an important part of exhaust-system construction.
This adapter is specified as 304 stainless steel, a widely used corrosion-resistant alloy for performance exhaust components. The polished finish complements stainless downpipes, headers and other custom exhaust hardware.
Proper installation, thread engagement and clearance remain essential. Stainless construction does not eliminate the need to protect the oxygen sensor and wiring from excessive exhaust heat.

Compatible Exhaust and Fabrication Applications
This universal-style M18 x 1.5 oxygen sensor adapter may be suitable for a variety of exhaust systems when the thread dimensions, sensor configuration and installation clearance match.
- Custom stainless steel exhaust fabrication
- Turbocharger downpipe assemblies
- Performance exhaust headers with compatible sensor bungs
- Custom fabricated exhaust pipes and collectors
- High-flow exhaust components used in lawful applications
- Race-only and off-road exhaust projects
- Custom oxygen sensor mounting and clearance applications
- Compatible narrowband and wideband oxygen sensor installations, subject to sensor requirements
Universal does not mean every vehicle. Confirm the M18 x 1.5 thread, sensor body size, connector routing, exhaust bung position and available space before purchasing.
Important Fitment and Clearance Checklist
- Verify the exhaust bung has M18 x 1.5 threads.
- Confirm the oxygen sensor has the correct mating thread.
- Measure the space around the sensor and adapter.
- Allow room for sensor wiring and connector routing.
- Keep wiring away from excessive heat and moving parts.
- Verify proper thread engagement and sealing.
- Confirm the adapter does not interfere with nearby components.
Installation Overview
- Allow the exhaust system to cool completely.
- Identify the intended oxygen sensor mounting location.
- Verify the existing exhaust bung uses M18 x 1.5 threads.
- Check that the adapter and sensor can be installed without interference.
- Install the adapter using appropriate tools and the correct sealing method for its design.
- Install the compatible oxygen sensor according to the sensor manufacturer's requirements.
- Confirm proper clearance, wiring routing and exhaust sealing before operation.
No cutting or welding is required when a compatible threaded exhaust mounting location already exists. Professional installation is recommended.

Important Emissions and Application Notice
This component is intended for lawful custom fabrication, racing, off-road, experimental or other permitted uses. It is not intended to defeat, bypass, disable or interfere with required emissions-control equipment or onboard diagnostic monitoring.
No guarantee is made that this component will prevent or correct diagnostic trouble codes or check engine lights. Vehicle owners and installers must verify compliance with all applicable emissions and vehicle regulations.
Frequently Asked Questions
What is a 90 degree O2 sensor spacer?
A 90 degree O2 sensor spacer is an angled threaded fitting that changes the mounting direction of a compatible oxygen sensor relative to its exhaust bung.
What makes this a shorty O2 sensor adapter?
The shorty configuration emphasizes compact packaging for installations where a longer straight extension may create clearance issues. Confirm actual dimensions against your available space.
What is the thread size?
The specified thread size is M18 x 1.5, a common oxygen sensor thread specification. Check both the oxygen sensor and exhaust bung before ordering.
Is this made from 304 stainless steel?
Yes. This SSAutoChrome model is specified as 304 stainless steel with a high-polish finish.
Will this fit my turbo downpipe?
It may fit a compatible downpipe equipped with an M18 x 1.5 oxygen sensor bung, provided the sensor and adapter have adequate installation clearance.
Can this be used with a wideband oxygen sensor?
Thread compatibility alone is not enough. Wideband sensors have specific mounting, heat and exhaust-exposure requirements. Follow the sensor manufacturer's instructions before using any adapter.
Does this require welding?
No welding is needed when a suitable threaded oxygen sensor bung is already present.
Will it eliminate a check engine light?
No such result is guaranteed. This product is marketed as a sensor-positioning component, not as an emissions-monitoring defeat device or guaranteed diagnostic repair.
How many spacers are included?
One shorty 90 degree O2 oxygen sensor spacer is included.
