It's quick and easy.
The Toyota 4Runner Oxygen Sensor is a hard-working part of your rugged Toyota. The Oxygen Sensor monitors the amount of oxygen in the exhaust stream and then relays that information to the engine-control computer, in order to keep the air/fuel ratio in your Toyota 4Runner at optimum levels, for maximum efficiency. The Toyota 4Runner is built for performance, whether you are talking about a four-wheel-drive model and off-road adventure, extra capacity for luggage, cargo and passengers, or towing ability. The 4Runner does it all and makes it look good! Your Toyota has an outstanding reputation for quality and durability, and you want to preserve these qualities by only installing high quality and durable parts on it.
