The NGK direct-fit oxygen sensor for Ford Aerostar (1986) replaces the original sensor and supplies continuous closed-loop feedback to the engine control unit to support correct air-fuel mixture, fuel economy and emissions monitoring. Constructed with advanced ceramic sensor technology and a 3-stage contaminant-resistant plasma jet plus deposit-trap overcoat, the sensing element is guarded against contamination to improve durability and OE compatibility.
