SM093-46 Straight Multi-hole Oxygen Sensor Adapter

The  straight multi‑hole oxygen sensor adapter is purpose‑built to resolve frequent false catalyst efficiency trouble codes after exhaust system retrofits. Manufactured from high‑strength stainless steel, this spacer is engineered for automotive aftermarket repair and modification scenarios. It tackles annoying check‑engine light issues caused by catalytic converter signal deviation, without large‑scale changes to your original exhaust setup.

Premium Stainless‑Steel Build for Harsh Exhaust Environment

Made of solid stainless‑steel material, this adapter delivers outstanding heat‑resistance and anti‑corrosion capability. It can sustain long‑time exposure to high‑temperature exhaust gas, resisting oxidation and exhaust‑gas erosion. Consistent mechanical performance is maintained even under repeated thermal cycling, extending service life in real‑world vehicle working conditions.

Optimized Multi‑hole Sampling Structure

Featuring multiple evenly‑distributed internal sampling holes, this spacer realizes balanced exhaust‑gas sampling for downstream oxygen sensors. Compared with single‑hole adapters, the multi‑hole layout optimizes airflow distribution, avoids skewed gas signal reading. It effectively filters misleading feedback signals that trigger OBD warning lights, solving fault codes including P0420, P0421, P0422, P0423, P0424, P0430, P0431, P0432, P0433 and P0434.

Universal Thread & Simple Screw‑in Installation

Equipped with industry‑standard M18×1.5 thread, the adapter ensures tight, leak‑free connection. Total length is 46 mm, well‑adapted for most vehicle exhaust layouts. No welding, cutting or extra modification is needed. Direct screw‑in installation saves plenty of time for auto repair shops and DIY car owners. It fits Japanese, European, American passenger vehicles for catalytic replacement and exhaust upgrade work.
