Engine Management Systems

Precision engineering. Advanced design. The highest OEM quality. These are the exceptional qualities you’ll find in DENSO’s Engine Management Systems (EMS) ranges for the aftermarket.

Including Lambda Sensors, Mass Air Flow (MAF) Sensors, Fuel Pumps, Exhaust Gas Recirculation (EGR) Valves and Exhaust Gas Temperature (EGT) Sensors, each of our EMS products features original DENSO technologies that guarantee a perfect first-time fit and reliable, superior performance on the road.

Why choose DENSO for EMS? As one of the world’s foremost pioneers and manufacturers of original automotive parts and systems, DENSO understands state-of-the-art engine management better than anyone else. For example we developed the world’s first Exhaust Gas Recirculation (EGR) Valve integrating an air intake throttle valve and an EGR valve, helping to make diesel engine emissions cleaner at half the size of conventional models. We launched the world’s first plug-in type Mass Air Flow meter inserted into the intake pipe wall, reducing the size and weight and aiding installation. We were also the first to introduce quantitative measurement to our Lambda Sensors, enabling them to sense both if the air/fuel mixture is too lean or too rich, and by how much. Such unrivalled expertise means you’ll find DENSO EMS products fitted as original equipment in many of the world’s leading vehicle marques.

This advanced DENSO engineering is now available to aftermarket customers in our replacement Engine Management Systems ranges. In fact, DENSO is the only company to make certain OE quality EMS applications available to the aftermarket, making many of our EMS products unique.
