## Description

M18x1.5 Stainless Steel Car Universal Oxygen Sensor Extender Spacer Adapter for emulatore+sonda+lambda : 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 !
Review: Worked a treat! - Worked a treat on my 2025 MT-07 when de-catting the exhaust system fitting an Akrapovic.
