NGK/NTK direct-fit oxygen sensor for the Acura RSX & Honda Civic Si. NTK supplies more than half of the world's original-equipment oxygen sensors, and this is a direct OE replacement with the correct connector, wiring length and mounting hardware for a plug-and-play install. Its zirconia sensing element gives the ECU the rich/lean feedback needed for closed-loop air/fuel control, and a 3-stage contaminant-resistant overcoat protects the element against poisoning for long, stable service.
