FAQ's
Diesel particulate filter backpressure is an important performance characteristic. High backpressure can increase fuel consumption and shorten the life of the diesel particulate filter. The Durafit diesel particulate filter is designed to be an exact replacement to the OEM part, including backpressure. Durafit has extensively tested the Durafit in the field and in our testing laboratory to ensure that the backpressure performance is equivalent to or better than the OEM product. You can be assured of great performance on every Durafit diesel particulate filter, as we use only OEM materials in our vertically integrated manufacturing process.

Fuel and oil contain inorganic additives to help protect your engine and extend the life of the oil. During the combustion process, they are turned into ash, which collects in the diesel particulate filter over time. Unlike the black carbon and soot in the exhaust, which is reduced during the regeneration process, the ash can only be removed by a cleaning device. This requires the diesel particulate filter to be removed from the engine. The cleaning interval varies for each engine manufacturer (and sometimes between engines from the same manufacturer) and can be found in your vehicle’s service guidelines. You should follow the engine manufacturer’s recommended cleaning intervals for your Durafit diesel particulate filter just like you would for the original diesel particulate filter.
Note that the amount of ash is directly related to the amount of oil an engine consumes. High oil consumption or high hours of service means more ash in the diesel particulate filter and may require more frequent cleaning.
