Pro-Line Diesel particle filter protector is a highly effective additive that reduces the build-up of particulates and thus increases the service life of the diesel particle filter. Vehicles used for city driving and those that drive short distances are especially affected by blocked diesel particle filters. When used regularly, the diesel particle filter remains clean and expensive repair and servicing times are avoided. Pro-Line Diesel particle filter protector ensures optimal fuel combustion and reduces the build-up of particulates. This also helps in reducing emissions.
