About NTK Lambda Sensors

NGK are the world's Number1 spark plug manufacturer so you wouldn't expect anything less from their technical ceramics division, NTK. NGK launched their first NTK Lambda Sensors in the 1980s and with the obvious benefits of more efficient running and reduced emissions the range has grown to cover a very wide range of vehicles indeed, some of which use NTK sensors as Original Equipment (OE). The wholesale uptake of catalytic converters has also made use of Lambda Sensors critically important as a means of protecting the sensitive catalyst.
The NTK sensor range includes Titania, Zirconia and Wideband sensor types, a sensor for every requirement. All NGK sensors have OE style connectors to ensure compatibility and ease of installation. You should be aware that standardisation of parts has resulted in the cable length of some sensors being significantly longer than the OE part which it replaces, this allows the same sensor to fit multiple vehicles rather than a single vehicle type. Each sensor is factory tested for quality and operation, eliminating the possibility of a genuinely faulty sensor being supplied.

Benefits of NTK Lambda Sensors

NGK NTK Lambda Sensor Box

NGK NTK Yellow Box Lambda Sensor

Tailored for each application - a good match for the OE part

Specification matches or exceeds that of the vehicle manufacturer

OE style connector block eliminates the possibility of wiring errors, poor connections and water ingress

Quick and simple to fit, saving time and money.

You can be confident in the NGK/NTK brand as a world leader in Lambda Sensor manufacture.

Every NTK sensor is certified by the German Technical Inspectorate for compatibility with the OE sensor type.

A note about NGK fitting position descriptions:
Most modern vehicles will utilise at least 2 Lambda Sensors.

Sensor Numbers:
Sensor 1 will always be the Upstream/Pre-cat/Regulating/Front sensor
Sensor 2 will always be the Downstream/Post-cat/Diagnoistic/Rear sensor

Bank numbers:
Bank 1 will always include cylinder number 1
Bank 2 will not include cylinder number 1
Most small engined vehicles will only have one bank. Six cylinder straight or V engines will normally have two banks.
ex. A sensor specified as Bank 1 Sensor 1 will be fittied to the group of cylinders which includes cylinder number 1 and will be a Pre-cat/Upstream/Regulating sensor.
Note: We would always maintain that the only safe way to ensure the correct replacement is to cross reference from the OE factory part number.
