Check fit first, then add a compact M18 × 1.5 adapter between a compatible downstream oxygen sensor and exhaust bung.
✨ Why You’ll Love It
Integrated Mini-Core Design
The adapter places the downstream sensor farther from direct exhaust flow and incorporates the pictured internal mesh/core structure.
Stainless-Steel Construction
The metal body is intended for the heat and corrosion exposure found around compatible exhaust fittings.
Two-Piece Set
The package contains two matching adapters for a compatible dual-sensor application or a spare, subject to vehicle fitment.
🏡 Where It Fits into Real Life
• Compatible downstream oxygen-sensor locations with an M18 × 1.5 interface
• Workshop inspection or repair after the actual fault has been diagnosed
• Modified or specialty exhaust configurations only where local rules permit
📝 How to Use & Care
1. Let the exhaust cool completely, secure the vehicle safely, and locate the downstream oxygen-sensor fitting. Professional installation is recommended.
2. Confirm an M18 × 1.5 thread match, available clearance, sensor-wire reach, and applicable emissions rules before removing any part.
3. Hand-thread the adapter into the compatible exhaust bung first. Do not force or cross-thread it; tighten to the vehicle or component manufacturer's specification.
4. Install the sensor into the adapter, route the wiring away from heat and moving parts, then check for exhaust leaks and diagnostic faults after installation.
🔎 A Closer Look
The current gallery shows a threaded metal body, hex wrench surfaces, a female sensor-side opening, and an internal perforated mesh/core. Inspect threads and sealing surfaces before installation, and discontinue use if the part is damaged, loose, or leaking.

❓ Frequently Asked Questions
Will it fit every vehicle?
No. M18 × 1.5 is only one part of fitment. Confirm the exhaust bung, sensor thread, surrounding clearance, wire reach, make, model, engine, and exhaust configuration before ordering.
Will it turn off a check-engine light?
No result is guaranteed. A warning light can have many causes; read the diagnostic codes and repair the underlying fault rather than relying on an adapter as a substitute for diagnosis.
Is it legal for road use?
Emissions and anti-tampering rules vary by jurisdiction and vehicle. Confirm legality before installation; do not use it to disable or bypass required emissions controls.
Is an oxygen sensor included?
No. The package contains two spacers/adapters only; oxygen sensors and installation tools are not included.
What return period applies?
Elarohome's current 30-day return policy applies. Any different return-period wording embedded in a supplier image does not replace the store policy.
