About LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension
What is LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension?
The LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension is a precision-machined stainless steel adapter designed to relocate oxygen sensors in exhaust systems. Engineered for vehicles with M18x1.5 threaded bungs, this 90-degree catted extender provides critical clearance when space is tight, especially in modified or high-performance builds. It's built for off-road, racing, or experimental applications and is not intended for street-legal highway vehicles.
Key features
- 90-Degree Angled Design — Allows optimal sensor positioning in tight exhaust layouts.
- Catted Stainless Steel Core — Includes a catalytic element to help manage emissions signals more effectively than hollow spacers.
- M18x1.5 Thread Standard — Universally fits most O2 sensor ports with 18mm x 1.5mm threading.
- Bolt-On Installation — No welding or modifications required; direct fit into existing bung.
- High Compatibility Rate — Proven to work on over 99% of applications, including Euro and exotic vehicles.
- Durable Construction — Made from high-grade stainless steel to resist corrosion and heat damage.
- Off-Road Use Only — Designed strictly for race, off-road, or experimental vehicles; not for highway use.
Who is LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension for?
This extender suits performance tuners, off-road builders, and DIY mechanics dealing with tight exhaust routing or intermittent P0420 (catalyst efficiency) codes. It's ideal when standard spacers fail due to sensor sensitivity. Users must verify physical clearance before installation. Not recommended for daily-driven street vehicles due to legal and emissions compliance restrictions.
How does LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension compare?
Unlike basic hollow O2 spacers, this catted version includes a catalytic element that improves signal stability on sensitive ECUs, especially in European and high-tune applications. Compared to cheaper alternatives, it offers superior fitment and durability thanks to stainless steel construction and precise threading. While functionally similar to other 90-degree extenders, its proven success rate across exotic platforms sets it apart. However, it remains incompatible with non-M18x1.5 threaded sensors without adapters.
Best use cases
- →Relocating O2 sensor in tight exhaust manifolds
- →Testing P0420 catalyst efficiency codes
- →Off-road vehicle exhaust modifications
- →Race car builds with custom exhaust routing
- →High-performance Euro vehicle tuning
Is LABWORK Catted Extender O2 Oxygen Sensor Angled Spacer 90 Degree 02 Extension right for you?
Buy this if you're a DIY tuner or builder working on a race, off-road, or experimental vehicle needing O2 sensor clearance. Confirm your sensor uses M18x1.5 threading and that space allows 90-degree placement. Not for street vehicles. Alternatives include straight spacers or ECU reflashing for code suppression.
How it compares: Compared to hollow O2 spacers, this catted version offers better signal management on modern, sensitive ECUs. It outperforms generic extenders in fit and durability, especially on Euro and high-performance platforms, but lacks versatility for non-M18x1.5 applications.

What is a catted O2 extender spacer used for?
▾
A catted O2 extender spacer relocates the oxygen sensor in the exhaust, providing clearance and using a catalytic element to help stabilize sensor readings, often reducing false P0420 codes in performance or modified vehicles.
Does this fit all O2 sensors?
▾
No, it only fits sensors with M18x1.5 threading. Confirm your vehicle's O2 sensor thread size before purchase. It is not compatible with other thread types without an adapter.
How does the catted element help with O2 sensor signals?
▾
The catted core contains a small catalytic converter that helps process exhaust gases before they reach the sensor, improving signal accuracy and reducing the chance of triggering a P0420 code.
Is this legal for street use?
▾
No, this product is designed for off-road, race, or experimental vehicles only. It is not legal for use on highway or emissions-controlled street vehicles in any jurisdiction.
Can I return it if it doesn’t fit?
▾
Returns are not accepted on used or test-fitted items. Ensure compatibility and clearance before installation, as the sale is final once the item has been handled or bolted on.
