A water/meth injection system can be huge benefit for boosted applications. Being able to run more boost means more power and more speed! The pump itself is the critical portion of the system and must be kept safely running. Keeping contaminants out means the pump keeps running smoothly and the lines and nozzle do not clog. Installing a filter like this one from AEM can keep some of the smallest foreign bodies out your system. Using a steel screen that will filter down to 40 microns is a small part that can prevent a big problem. The screen can be cleaned as needed and reused.
