Don't replace your diesel particulate filter; clean it by using Liquid Moly's DPF Cleaning Kit. The DPF Cleaning Wand and 5 spray tips (one piece of the kit) is for cleaning clogged diesel particulate filters in passenger cars, SUVs light to medium duty trucks including those powered by Duramax and Cummins engines. The wand delivers both the Cleaning and Purge fluids to the DPF to clean and then flush dissolved containments out of diesel particulate. Returns optimum vehicle handling, engine performance and lowers fuel consumption. Regular cleaning in combination with flushing can help avoid expensive repair costs including the replacement of the diesel particulate filter which can cost upwards of $3,000. Liquid Moly's DPF Cleaning Wand must be used in conjunction with DPF Cleaning Fluid (LM 5169), DPF Purge (LM 5171) and the Pressurized Spray Gun (LM 7946).
