Fuel Dongle PP-69 ST12 690 SM/SMR/SMC > 2021 -Description This kit allows remove the oxygen sensor or lambda probe from the exhaust. Oxygen sensors or lambda probes installed in the exhaust limit engine performance since its function is to control gas emissions. Due to the pollution regulations, the stoichiometric mixture (AFR) is raises in a certain RPM range, causing the engine to go poor gasoline. An engine with a lean mixture will be unstable, will jerk, overheat and have a noticeable loss of
