NGK Toyota Highlander 2007 Direct Fit Oxygen Sensor

This is a direct fit oxygen sensor from NGK for your 2007 Toyota Highlander. Oxygen sensors are a key part of your vehicle's onboard diagnostic system. They help keep your engine running at its best, which means better fuel economy and fewer harmful emissions. This sensor constantly sends information to your car's computer about the air-fuel mixture, helping it make adjustments and also alerting you if there's a problem with how the engine is delivering fuel or if the catalytic converter isn't working right.

NGK, a major supplier of OEM oxygen sensors, builds these with an advanced ceramic element. This ceramic is protected by a special coating that acts as a trap for contaminants and deposits, helping to prevent the sensor from failing prematurely due to poisoning. They work closely with car manufacturers from the start of development to ensure their sensors perform well and resist common failure points.
