Product Details

Our front Land Rover Discovery 2 oxygen sensor (Part # MHK100920) has been made specifically for use in your Land Rover Discovery Series 1999 – 2004. You can be assured this high quality replacement O2 sensor will fit your Rover when you purchase from Atlantic British.

New oxygen sensors can reduce emissions, maximize fuel economy and boost engine performance. With gas prices skyrocketing, you can’t afford to drive around with outdated O2 sensors!

Each Land Rover Discovery 2 requires four (4) oxygen sensors. Two of these sensors are mounted in front of the Land Rover’s catalytic converter and two behind it. The front O2 sensor or pre-cat sensor measures the oxygen levels of gases leaving the combustion chamber. The amount of fuel entering your engine is then adjusted based on the oxygen levels of your exhaust gas. As an oxygen sensor ages, it becomes contaminated, reducing its ability to read and react to your vehicle’s O2/gas mixture. A sudden drop in fuel economy and a “check engine light” are common symptoms of a failed O2 sensor.

We recommend replacing your oxygen sensors every 60k miles. O2 sensors should be bought in pairs; two front sensors and two rear sensors. For Discovery 2 rear sensors Click Here.

Reasonably priced, was looking for something better than Bosch (time will tell). I’ve made many purchases from you in the past, and will continue to do so.

Great replacement item! With the help of the Atlantic British tech video, I had my front O2 sensors replaced in no time flat! And these sensors do a good job without having to shell out $200 a pop for the OEM ones. Thanks Atlantic British!

Perfect fit and instant performance upgrade over old worn sensors. Should have done this sooner.

I had previously purchased a cheaper aftermarket unit of the intraweb and it was not even recognised by the Disco - so a P0150 code right away. Purchased a pair from Atlantic, although only one code up (will do other at weekend) installed a breeze and it just worked. no messing, cleared codes, so far so good.
