Discount BMW 325I Parts

The BMW 325I achieves optimum performance within certain parameters, and scheduled maintenance should be performed as needed. The oxygen sensor for example is one of those BMW 325I parts that seems like a minor thing. Nonetheless, it can have a great effect on engine performance and efficiency.

Achieving the best fuel mixture - that is, ratio of liquid fuel to oxygen - is a balancing act that involves all the BMW 325I parts that make up your vehicle’s fuel delivery and exhaust system. When the mixture is too lean, it means poor power and performance. A mixture that is too rich, on the other hand can decrease gas mileage and increase exhaust emissions as well as cause carbon build-up on the valves. By detecting the amount of leftover oxygen in the exhaust gases, oxygen sensor works with other BMW parts, particularly the fuel injectors. It sends an electronic signal to the fuel-injection system, which automatically adjusts the mixture for the driving conditions at the moment. A damaged or defective oxygen sensor can cause lower engine performance, decreased fuel economy and polluting exhaust. As with all BMW 325I parts, the old oxygen sensor should be replaced with a genuine factory unit. Some discount BMW 325I parts are marketed as “rebuilt” or “remanufactured.” When done by a reputable German company, these rebuilt components easily meet factory standards, but cost significantly less. When it comes to parts that wear out around 100,000 miles – the alternator, water pump and starter – this is an acceptable and less expensive way to go.
