DeatschWerks has built the most comprehensive injector offering in the industry. The DW line-up covers high impedance, low impedance, GDI, EFI, side feed, and top feed. DW not only works directly with Bosch Performance to deliver a complete EV14 line up, but also offers Denso, SMP, JECS, and Delphi options. DW high flow fuel injectors are only offered in balanced sets processed through our multi-point dynamic flow testing system. This system replicates the dynamic frequencies and pulse widths your injectors experience in your high performance engine to create a set of injectors balanced to within 2% flow variation across the low, transitional, and linear ranges of pulse widths. DW knows that proper data is required for proper tuning. All DW injectors are fully characterized in-house via SAE J1832 standards. Injector data is available in General Characterization Summaries and Application Specific formats. See website for details. All DW injectors are backed with a comprehensive 3-year warranty.
