Engine Filters

Delphi’s extensive range of filters brings together the brands Diavia and Diesel’s CAV, providing a filtering solution for over 97% of the cars and light commercial vehicles on European roads.

Air, Oil and Fuel filters are fundamental to the performance of an automotive engine.

In order that an engine meets fuel efficiency economy and emission targets, these three filters must remove all harmful contaminants and provide peak performance through the vehicle manufacturer's recommended service period.
Delphi Air Filters are designed to operate in hostile environments within extreme temperature conditions and prevent contaminants from entering the engine management system.

Delphi's Oil Filters are designed to handle large volumes of oil, removing particles of metal, carbon and other debris resulting from the combustion process. These filters are available with many optional features depending on engine requirements. For example, features such as anti-drain, element relief and anti-syphon valves or anti drain tubes.

Delphi's Petrol Fuel Filters are designed to protect an engine's sophisticated petrol injection equipment and engine management systems by trapping contaminants that may be present in the fuel, or rust and sediment from the fuel tank.

Delphi's range of Diesel Fuel Filters previously sold under the "CAV" brand, serve both Original Equipment and the Aftermarket. By working closely with the world's leading manufacturers, Delphi's diesel product range supports over 550 vehicle and engine manufacturers applications from Audi cars to Volvo buses. Delphi's diesel fuel filters protect diesel-injected engines from contaminants as well as removing small droplets of water often found in diesel fuel.
