Bosch Oxygen Sensor P/N:16809
Bosch 15848 oxygen sensor for the 2004-2005 Suzuki Forenza 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust and sends air-fuel-ratio readings to the ECU. This upstream sensor helps the engine hold stable combustion control and keep emissions down.
A failing oxygen sensor can show up as a check engine light, a rough idle or lower fuel economy. These signs alone do not prove the sensor is the problem, since an exhaust leak ahead of it can throw off the readings too.
It fits the 2004-2005 Suzuki Forenza 4-cylinder 2.0L and the 2005 Suzuki Reno 4-cylinder 2.0L. This listing is one sensor, and the 2004-2005 Suzuki Forenza 4-cylinder 2.0L takes one.

Does this oxygen sensor come with anti-seize already on the threads?
Yes. The threads have pre-applied conductive anti-seize, and the connectors are direct-fit for quick installation.
