DPF (diesel particulate filter) is designed to serve an important purpose, that being capturing soot and other particulates from the exhaust before they have a chance to be released into the environment. If the DPF cannot be properly cleaned at the necessary intervals, then it’s going to clog up. When it clogs, it won’t just lead to maintenance with the DPF, but potentially with the engine as well. DPF also limits the performance of the engine, which can lead to performance and production issues. After installing a DPF delete kit, you’ll notice significantly increased horsepower and fuel economy. As an added bonus, you’ll add at least a few extra years onto your vehicle’s life.
