Denso Direct Fit Oxygen Sensors, sometimes referred to as Lambda or O2 sensors or probes, are designed to be a 'plug and go' replacement for Original Equipment (OE) or competitor brand Oxygen sensors. This means you do not have to perform any cutting and reconnecting of cables, or need to reuse the original sensor connector. The correct connector for your vehicle's wiring loom is already attached to the direct fit replacement sensor.
Flange fitting type sensors are supplied with a gasket if required and sensors with a threaded fitting are either pre greased at the factory or are supplied with a sachet of suitable grease.
Simply disconnect your existing sensor from the vehicle's wiring loom, this is usually located in the engine bay and, using a suitable tool such as a Laser Lambda sensor socket for M18 threaded sensors, or the correct sized socket for sensors with flange fitting, carefully remove the existing sensor. Using the same tool, install the new sensor core, taking care not to damage the cables or the sensor body, connect back into the wiring loom and you're good to go.
Note that some vehicles may require an ECU reset in order to recalibrate engine management systems for the new sensor, this usually entails disconnecting the battery for a number of hours, overnight is usually sufficient.
