XS-POWER 90° O2 OXYGEN SENSOR SPACER
The XS-POWER 90 Degree O2 Oxygen Sensor Spacer / Extender is a compact angled exhaust adapter designed to reposition a compatible oxygen sensor where additional clearance or alternate sensor positioning is required.
Featuring the widely used M18 x 1.5 oxygen sensor thread, this 90° O2 sensor adapter is designed for compatible exhaust systems, including performance headers, turbo downpipes, exhaust pipes and custom exhaust applications.
The 90-degree angled configuration can be especially useful where a straight O2 sensor extension creates clearance problems around the vehicle floor, transmission tunnel, exhaust system, chassis or surrounding components.
Finished in a clean high-polish metal finish, the XS-POWER O2 spacer combines compact dimensions, common M18x1.5 threading and a simple threaded installation for compatible applications.

WHY A 90 DEGREE O2 SENSOR EXTENDER
A conventional oxygen sensor installs directly into the exhaust bung. On some custom or performance exhaust configurations, the sensor's original position can create clearance or positioning challenges.
The XS-POWER 90° angled O2 sensor extender changes the orientation of a compatible sensor approximately 90 degrees from the original mounting point.
This can provide a useful installation option on compatible turbo downpipes, performance headers, custom exhaust systems, test pipes and other fabricated exhaust applications.
⚙️ UNIVERSAL M18 x 1.5 O2 SENSOR THREAD
The spacer uses the popular M18 x 1.5 oxygen sensor thread size found on many automotive oxygen sensors and exhaust O2 sensor bungs.
Always verify the actual thread size and available installation clearance on your vehicle before ordering.

90° O2 SENSOR SPACER FAQ
What thread size is the XS-POWER O2 sensor spacer?
The thread specification is M18 x 1.5. Always verify the thread size of your oxygen sensor and exhaust bung before ordering.
Is this a 90-degree O2 sensor adapter?
Yes. This model uses a 90-degree angled configuration to change the orientation of the oxygen sensor.
Why use an angled O2 sensor spacer?
A 90-degree adapter can help reposition a compatible oxygen sensor where a straight installation creates clearance or packaging problems around the exhaust, chassis or surrounding components.
Will this fit every vehicle?
No product should be assumed to fit every vehicle. This is a universal-style component intended for compatible M18 x 1.5 oxygen sensor applications. Thread size, sensor dimensions and physical clearance should be checked before ordering.
Can this be used on a turbo downpipe?
It can be used on compatible turbo downpipes equipped with the appropriate M18 x 1.5 oxygen sensor bung, provided adequate physical clearance is available.
Can this be used with a performance header?
Yes, on compatible header and exhaust applications using the appropriate M18 x 1.5 O2 sensor connection.
Does installation require welding?
No welding is required when installing the adapter into an existing compatible threaded M18 x 1.5 O2 sensor bung.
What are the approximate dimensions?
The spacer measures approximately 75mm long × 50mm wide.
Is the oxygen sensor included?
No. The oxygen sensor and exhaust components shown for demonstration purposes are not included.
Is professional installation recommended?
Yes. Professional installation is recommended, particularly on modified or custom exhaust systems.
