V4 Lambda Sensor 584344

Fitment - RSV4 09-14, Tuono V4 11-16

Genuine Aprilia Lambda sensor, item number 584344.

A Lambda or oxygen (O2) sensor functions by measuring the amount of oxygen in the exhaust system.

It works alongside the ECU to maintain and adjust the air to fuel mixture until it reaches close to a near perfect ratio therefore preventing the mixture from becoming either too lean, which is high in air and less in fuel, or too rich, which is high in unburnt fuel and less in the air. In either of those cases, the combustion process is not efficient.
