• 【M18 x 1.5 Thread Compatibility】Designed with a standard M18 x 1.5 thread, this oxygen sensor spacer is suitable for many compatible O2 sensor ports. Please check the thread size, available installation space and sensor position before purchase.
• 【46.5 mm Extended Spacer Design】The 46.5 mm body increases the distance between the oxygen sensor and the direct exhaust flow. It may help reduce unwanted sensor readings in compatible modified exhaust systems, depending on the vehicle and installation conditions.
• 【Stainless Steel Construction】Made from stainless steel for resistance to corrosion, cracking and high exhaust temperatures. Precision-machined threads support secure fitting and repeated installation during vehicle maintenance or exhaust system work.
• 【Straight-Through Design Without Filter】This oxygen sensor adapter uses a simple hollow spacer structure and does not contain a filter element or catalytic insert. The straightforward design provides additional sensor spacing without adding internal filtration components.
• 【Simple Threaded Installation】The adapter screws directly into a compatible O2 sensor port, after which the oxygen sensor is installed into the adapter. No specialist modification is normally required, but professional installation is recommended when compatibility is uncertain.
