Mach Series Injectors for the 24 Valve VP44 engines come in many standard sizes, but we can make any size you need. These are the longest produced performance injector in the business. Designed in 2001. Many are still on the road today, 17 years later. Every Mach injector uses a Sac style nozzle and either 5, 6, 7, or 8 EDM machined spray holes depending on application. All Mach injectors have a 7 year warranty - the longest in the business. Many original Mach injectors are still in service. The nozzle is a high quality European product, designed and manufactured with the best alloy steels. Our hydro-erosion technique on the nozzle gives you the best performance and the lowest smoke output per hp in the business.
