Delphi Filtration. 

Filtering out the Good from theBad.

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

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.

A Complete Aftermarket Solution.

We bring this same expertise to the aftermarket with an extensive range of diesel filters for car, light commercial, heavy duty and off-highway applications, as well as OE quality cabin air and petrol filters. But whether engineered for an OE or aftermarket application, we apply the same stringent validation, manufacturing and testing procedures. Every filter adheres to high quality standards for performance you and your customers can trust.

Tech Tips for Fewer Diesel Filter Comebacks. 

> Always clean the top of the filter and any connections before starting work as this helps to prevent contamination.

> If your filter has a heater element fitted, remember to transfer this over to the new filter before replacing.

> Always replace o-rings and seals on fuel heaters and water sensors.

> When removing the old filter, cap the fuel pipes to prevent any contamination from entering the system. 

> Empty the contents of the old filter into a clean container. If the content is not clear, full of particulates, or has high water content, then the system must be cleaned out from the tank to the filter.

> If the particles are of a metallic nature, a full system overhaul will be required. Tip, ferrous metallic particles can be identified using a magnet under the base of the container.

> On fitting the new filter, always remember to prime the system prior to starting the engine. Fit a priming bulb or use the pre-installed primer on some vehicles to prime the fuel system.
