## Description

M18x1.5 O2 Sensor Spacer - Stainless Steel Oxygen Sensor Extender Adapter for Universal Car - Lambda Sensor Filter Spacer : desertcart.co.uk: Automotive

Review: Did the trick. - With the engine warning light coming on periodically, (following an OBD2 scan) it became clear that I was having problems with my catalytic converter. After fitting this device to the downstream O2 sensor the engine warning light stayed off, (and with the use of a catalytic cleaner) allowed me to pass the MoT test. Well worth the money !
