Many people perform a tune up on their engine and forget the Oxygen Sensor! A professional mechanic can tell you how important it is to replace:
This sensor monitors the amount of air in your exhaust and sends a signal to the engine computer so it can regulate the air/fuel mixture of the engine for best economy, emissions, and Catalytic Converter life.
Oxygen Sensors (sometimes called "02 Sensors") degrade gradually over time, not all at once, so your M3 could be robbed of power and consuming excess fuel without you knowing it! Replacing this sensor on time is the only way to keep your very expensive E30 M3 catalytic center section from failing early on.
- OEM manufactured for superior fit and quality
- Long lasting
- Specific to the E30 M3 / S14
- Much better price than a dealer or parts store
VAC Tech Tip:
The E30 M3 has no "check engine light" for an O2 sensor falt as 1995-on vehicles do.
Oxygen sensors should be replaced every 60-80k miles as a part of your preventative maintenance routine.
