M18x1,5 Bung 34mm O2 O2 Oxygen Sensor Test Pipe Extension Extender Adapter Spacer

90° O2 Oxygen Sensor Spacer Engine Light CEL Check Bung Mini Catalytic Converter Euro 5 standard

I ordered 2/two mini cat adapters in one order. I received two different styles. One didn’t work because the O2 sensor didn’t fit in the hole of the adapter, but what looked like an updated version worked perfect. I have ordered them in the past and had to modify them to make it fit the sensor. They do keep the engine light off and work a long time.

This part is exactly what I was looking for and is high-quality would highly recommend it for the purpose that it serves

Installed this Spacer and then the 02 sensor into it. Cleared my check engine light almost instantly.

Works perfectly
