This is Agency Power AP-RZR-INJ Siemens Deka 80LB Fuel Injector Set Polaris RZR XP Turbo Upgrade. Manufactured by Agency Power.
Upgrade your Polaris RZR XP Turbo injectors with these Siemens Deka 80lb injectors. Equivalent to 830cc, these are quite the upgrade from the stock 2016 48lb or 2017 55lb injectors. This popular injector upgrade used by many tuners worldwide is perfect for those looking to improve the fueling on their RZR Turbo XP. The injectors are 48mm from end to end which give them the nick name "shorrty" injectors. They are a direct replacement for the stock injectors. The high impedance injectors are very linear and controllable at low pulse widths. This allows you to use a larger injector than normal without hurting your idle or low speed drivability. These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.
