SM091 90° Angled Oxygen Sensor Spacer

The 90° angled oxygen sensor spacer is engineered to solve the most difficult installation conflicts for heavily modified exhaust systems. When exhaust pipes, sub‑frames or chassis structures block the original vertical mounting direction, this 90‑degree elbow adapter reorients the oxygen sensor. It avoids physical interference without cutting or bending exhaust components, and assists in resolving catalyst‑related warning codes for auto repair and retrofit scenarios.

Robust Stainless‑Steel Build for Under‑Vehicle Conditions

Fabricated from high‑strength stainless steel, this 90‑degree elbow spacer delivers outstanding heat‑resistance, vibration resistance and anti‑corrosion performance. It copes with continuous high‑temperature exhaust exposure and road‑side corrosive substances. Even with frequent thermal expansion and contraction, the adapter maintains structural integrity and long service life in harsh undercar environments.

90° Elbow Steering for Extreme Limited‑Space Installation

Its rigid 90‑degree bent structure converts installation direction between vertical and horizontal orientation. For vehicles with highly complex exhaust layout, where straight or 45° adapters still cannot avoid chassis collision, this elbow design provides a reliable fit solution. It creates sufficient clearance for oxygen sensor assembly, eliminating mounting obstacles in narrow under‑car spaces.

Standard Thread Specification & Reliable Sealing Performance

Adopting universal M18×1.5 male and female threads, it perfectly matches mainstream automotive oxygen sensors. Strict CNC thread processing guarantees precise fit after torque tightening, effectively preventing exhaust leakage which may trigger extra OBD errors. The adapter helps eliminate fault codes: P0420, P0421, P0422, P0423, P0424, P0430, P0431, P0432, P0433 and P0434.

Wide Application & Simple Screw‑in Assembly

Designed for modified cars with narrow installation clearance, it fits most European, American and Japanese passenger vehicles. Direct screw‑in installation skips complex modification procedures, improving working efficiency for repair shops and DIY car tuners. Widely used in exhaust upgrade, catalytic converter replacement and emission fault troubleshooting.
