What is the DPF and is it worth doing a DPF Delete? Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) for emissions reasons, however there are a few disadvantages to this device; including constant maintenance and repairs.

Therefore, when you remove this filter, the fuel flows much easily and faster, increasing the overall fuel mileage.
