S&S Diesel Motorsport, the creator of the original Disaster Prevention Kit for the 6.7 Power Stroke, is at it again with a much-improved second-generation kit. Since its debut in 2016, the original S&S 6.7L Power Stroke CP4 Bypass Kit (Disaster Prevention Kit) has safeguarded thousands of injectors from CP4 debris. Being a company founded by fuel system engineers, S&S Diesel Motorsport has the ability, and responsibility, to offer the best solutions to fuel system problems. While the original bypass kit offers really good protection from a CP4 failure, the last four years have given the S&S engineers plenty of time to discover and eliminate potential problems.
