The first Chevy Impala came out in 1959, and was almost an instant classic (in fact, those early models are greatly sought after by collectors even today). For awhile during the 1960's, it was the most popular full-sized car in the U.S. Oxygen sensors weren't part of the exhaust system back in those days - gas was cheap and plentiful, and folks weren't thinking too much about air pollution (hey, we didn't know any better!) Today, with fuel economy and air quality now on most people's minds, the Chevy Impala Oxygen Sensor has become an important key to increasing fuel economy and reducing emissions.

An ideal fuel mixture will allow the engine to run at maximum power while putting out the smallest amount of polluting exhaust. A leaner mixture results in lower emissions, and is fine for level, open-highway driving in mild weather.

However, when the engine is under a heavy load, or the weather is cold, the engine requires a richer mixture. It's an ongoing balancing act for your vehicle's systems. The Chevy Impala Oxygen Sensor facilitates this process by measuring the amount of oxygen in the exhaust. Based on the data, it delivers an electronic signal to the fuel-injection system, causing the injectors to adjust the mixture for the current driving conditions. A damaged or defective oxygen sensor can adversely affect engine performance, reducing power and gas mileage while increasing emissions. If this is your case, a new Chevy Impala Oxygen Sensor may be needed.We always offer great discounts on a complete line of genuine Chevy parts, in stock and ready to ship - so log on and order yours today.
