The aqxreight Oxygen Sensor Spacer Adapter is an oxygen sensor spacer designed to reduce false catalytic-converter warnings and help clear P0420 codes. Tighter sealing and a precise fit give reassurance that oxygen sensor readings remain accurate on the road. Is it the right repair for your vehicle?
⚡ At a Glance
- • Sealing Performance: Outstanding sealing that prevents air or gas leakage around the oxygen sensor
- • Best for: Owners facing P0420 catalytic-converter codes who need to isolate sensor readings
- • Not ideal for: Vehicles without M18 x 1.5 O2 sensor threads or incompatible thread sizes
Universal M18 x 1.5 adapter aimed at reducing P0420 catalytic-converter fault codes. Optimised channels and tight sealing help oxygen sensors sample exhaust gases more accurately.
Reduce false P0420 codes - with M18 x 1.5 compatibility
Designed for most vehicles that use M18 x 1.5 oxygen sensor holes and intended specifically to address P0420 catalytic-converter codes. Compatibility targets the common thread size used by many O2 sensors.
Helps isolate the oxygen sensor so engine control units read exhaust composition more reliably on compatible vehicles.
Reliable sealing under heat - with a unique gasket design
A tailored sealing geometry forms a tight barrier that prevents unwanted air or gas ingress, while materials have been selected to resist the high temperatures and chemical exposure inside the exhaust system.
Prevents external air from skewing oxygen readings, reducing false check-engine lights and intermittent sensor faults.
Consistent sensor sampling - with optimised gas-flow channels
Internal channels and pathways are engineered to guide exhaust gases past the oxygen sensor, allowing rapid and representative sampling of the exhaust stream.
Faster, more accurate sampling helps the engine management respond correctly to fuel–air changes and reduces erratic sensor reports.
✨ The 4 Key Reasons for aqxreight Oxygen Sensor Spacer Adapter
- M18 x 1.5 compatibility - Fits most vehicles using the common M18 x 1.5 sensor thread
- High-temperature-resistant materials - Withstands exhaust heat and chemical exposure for longer service life
- Optimised gas-flow channels - Allow oxygen sensors to sample exhaust gases more accurately and quickly
- Precise dimensional engineering - Ensures a snug fit that reduces misalignment and prevents leaks

❓ Frequently Asked Questions
Q: Will this adapter fix a P0420 check-engine light?
A: The adapter is intended specifically to solve a P0420 code related to catalytic-converter failure, according to the product description. Results depend on whether the fault stems from sensor sampling rather than an actual converter failure.
Q: What thread size does the adapter require?
A: Designed for vehicles with M18 x 1.5 oxygen sensor holes, which covers most standard O2 sensor thread fittings.
Q: Is the adapter durable enough for exhaust conditions?
A: Materials are described as selected to endure high temperatures and chemical exposure in the exhaust system, and the design emphasises long-term integrity.
🏆 Our Verdict
Suitable for drivers and mechanics seeking a targeted fix for false catalytic-converter faults on vehicles with M18 x 1.5 sensors. Enhanced sealing, heat-resistant construction and optimised gas flow combine to make oxygen sensor readings more reliable. While suitability depends on vehicle compatibility, the adapter can reduce unnecessary diagnostics and offer modest long-term value when used where applicable.
