## Description

Wynn's 25692 Catalytic converter and oxygen sensor cleaner

Review: Works brilliantly - Brilliant , cleared the engine light on our Jazz , very happy
Review: Erased cat and O2 sensor faults - Incredible result. Poored a bottle on a full tank and 50 miles later my obd scanner found 0 issues. Before had catalyst and o2 sensor faults + engine light. To be honest i 1st used on a full tank the wynns blue bottle, seen a bit of better response on the throttle but errors didnt go away. Second refill with the black bottle sorted out everything.
