Item Description

Denso Narrowband o2 Sensor with 18mm x 1.5. This sensor can replace the narrowband stock o2 sensor on any 1JZ, 2JZ, or 7M engine. It has the same thread as most wideband sensors, so it will thread into many aftermarket downpipes that have a wideband bung. This is a brand new Denso brand sensor, with crimp connectors to attach it to your old sensor's connector wires. The blue wire is the narrowband output. The two black wires are non-polarized 12v heater wires. Works with most Toyota vehicles that use a 3 wire o2 sensor.
