Walker Products 250-24093 oxygen sensor for the 1996-2004 Acura RL V6 3.5L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. It is a four-wire, narrow-band, direct-fit design made for its specific position.
A failing sensor can show up as a poorly running engine, higher fuel consumption or exhaust emissions, or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, a visual check done with the engine off and cool. This listing is one sensor for one upstream position.
Beyond the 1996-2004 Acura RL V6 3.5L, it is listed for a wide range of Acura models, including the 1991-1999 NSX V6 3.0L and the 1996-1998 TL V6 3.2L. Open the Buyer's Guide tab to check your exact model and engine.

Build and materials
Is this Acura TL oxygen sensor right for a 1996-1998 model with the V6 3.2L engine?
Yes. Walker Products 250-24093 is listed for the 1996-1998 Acura TL V6 3.2L, in the upstream rear or upstream front position.
Is this the right oxygen sensor for a 1996-2004 Acura RL V6 3.5L?
Yes. 250-24093 is listed for the 1996-2004 Acura RL V6 3.5L. For other Acura models and engines, open the Buyer's Guide tab.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band, with four wires and an M18 - 1.5 thread. Walker Products 250-24093 is a direct-fit design.
Can a failing upstream oxygen sensor make the engine run poorly?
Yes. A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. A shop can test the sensor and its circuit.
What does the coating on the sensor electrodes do?
It keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces. The electrodes themselves are made of a gas-permeable platinum layer.
