The NGK direct-fit oxygen sensor for Acura RLX (2014–2017) provides the ECU with continuous closed-loop feedback to help control the air-fuel ratio, support fuel efficiency and monitor emissions. Constructed with an advanced ceramic sensing element, it employs a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to shield the element from contaminants and improve long-term resistance to failure for reliable diagnostics.
