  • LR3 / Discovery 3 V8 4.4L | '05 - '09
  • LR3 / Discovery 3 V6 4.0L | '05 - '09
  • Range Rover Sport | '06 - '09
  • Range Rover Sport Supercharged | '06 - '09

This front oxygen sensor replacement (Part # MHK500840) has been designed for use in LR3 2005 – 2009, Range Rover Sport 2006 – 2009, and Range Rover Sport Supercharged 2006 – 2009 models. Unlike cheaper alternatives that require splicing and splitting, LR3 and Range Rover Sport O2 sensors from Atlantic British come with the right connectors to fit your Rover.

Range Rover Sport, LR3 and Range Rover Sport Supercharged models require four (4) oxygen sensors – two front sensors and two rear sensors. The front sensors, or pre-cat sensors, measure the oxygen levels of gases leaving the combustion chamber and make adjustments based on the oxygen levels of your exhaust gas. As your oxygen sensor ages it loses its ability to measure oxygen levels in exhaust gases. This typically results in a drop in fuel economy and a “check engine” light warning on your Rover’s dash. Atlantic British recommends changing your oxygen sensors every 60k miles.

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 With gas prices skyrocketing, you can’t afford to drive around with outdated O2 sensors!

It is best practice to replace all four oxygen sensors at once. LR3, Range Rover Sport and Range Rover Supercharged models have specific left and right designations for their rear O2 sensors. It is important that you pay close attention to the vehicle applications when selecting your rear replacement sensor.

LR3 (2005 – 2006), Range Rover Sport (2005 – 2006) Range Rover Sport Supercharged (2005 – 2006): Right Rear and Left Rear

LR3 (2007 – 2009), Range Rover Sport (2007 – 2009) Range Rover Sport Supercharged (2007 – 2009): Both Right and Left Rear oxygen sensors.
