Walker Products Oxygen Sensor P/N:350-34166
Walker Products 350-34162 oxygen sensor for the 1986-1987 BMW 735i 6-cylinder 3.5L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This upstream sensor is a direct-fit, narrow-band design with four wires.
A failing sensor can show up as a rough-running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though damage to the wiring harness or the connector can be behind the same signs, so look both over for physical damage first.
This sensor fits the 1986-1987 BMW 735i 6-cylinder 3.5L and the 1986-1987 BMW L7 6-cylinder 3.5L. The listing is one sensor, and the 1986-1987 BMW 735i 6-cylinder 3.5L takes one.

Build and materials
Does the Walker Products 350-34162 oxygen sensor fit the 1986-1987 BMW 735i 6-cylinder 3.5L?
Yes. Walker Products 350-34162 fits the 1986-1987 BMW 735i 6-cylinder 3.5L as an upstream sensor, and it also fits the 1986-1987 BMW L7 6-cylinder 3.5L.
Is the 350-34162 oxygen sensor narrow-band or wideband?
Walker Products 350-34162 is a narrow-band sensor with four wires, supplied as a direct-fit part.
What does the coating on this Walker Products oxygen sensor do?
The electrodes carry a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
What problems can a failing Walker Products 350-34162 upstream oxygen sensor cause?
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light.
Is this oxygen sensor an upstream or downstream unit?
Upstream. Walker Products 350-34162 is listed in the upstream position.
