Delphi Filtration. Filtering Out The Good From TheBad.

We Don’t Just Design The System.We Protect It Too.

The Delphi Difference.

With modern diesel engines now injecting fuel at pressures of up to 2,200 bar, and injector tolerances being measured in microns, even the smallest amount of dirt, air, water or waxing can cause a problem. The good news is, because we design the system, we also know what it takes to protect it. Backed by over 100 years of OE heritage, Delphi diesel filters are designed with patented OE technology and high efficiency media for optimum filtration performance. We supply OE applications for the world’s leading manufacturers including Citroën, Dacia, Fiat, Ford, Hyundai, Jaguar, Kia, Land Rover, Mazda, Mini, Nissan, Opel/Vauxhall, Peugeot, Renault, Ssangyong, Suzuki and Volvo.

  • Designed, engineered and manufactured to provide the same levels of filtration performance and durability, as demanded by the vehicle manufacturer.
  • Extensive range of OE quality diesel, cabin and petrol filters.
  • Coverage of car, light duty, heavy duty and off-highway applications.
  • Feature the very latest filtration technology.
  • Diesel and petrol filters perform to ISO standards for durability, water separation and particle removal efficiency.
  • Support change intervals up to 60,000 miles.
  • 100% tested prior to despatch.
  • Aftermarket portfolio of over 700 parts covering more than 19,000 applications.
