NGK Acura EL 2005-2004 Direct Fit 4-Wire A/F Sensor

NGK is known worldwide as a leading supplier of original equipment oxygen sensors, and this direct-fit Air-Fuel Ratio (A/F) sensor is built with that same OE expertise. This 4-wire sensor is crucial for your vehicle's on-board diagnostic system, working to keep your engine running at its best. Unlike older switching sensors, this wideband A/F sensor gives your car's computer the exact information it needs about the air-fuel mixture, allowing for continuous and precise adjustments to maximize combustion efficiency, improve fuel economy, and minimize harmful emissions.

The heart of this sensor is its advanced ceramic element, which NGK controls from raw material to the finished product. This ceramic is protected by a 3-stage coating that resists contaminants and deposits, helping to prevent poisoning and ensure a long service life. Because it's a direct-fit part, it's designed to install easily into your existing wiring and exhaust system, making it a solid option for vehicles like the Honda Civic, Subaru Baja, and Subaru Forester, among many others.
