      Description

      Supercharge Your Mustang. Up your Ford Mustang’s power with this Fuel Injector Clinic Fuel Injector Set. Thanks to the latest technology, these fuel injectors provide great drivability with shot pulse width repeatability and great linearity. The kit includes all the O rings needed for installation. If your Mustang was made before 2005, you might need to separately order pigtails or plug & play adapters for installation.

      Fully Tested. Each fuel injector is flow tested at 43.5psi at 90-degree fuel temps to ensure each matches within 1%. All injectors are individually numbered, and you're provided the test results for each on the provided detailed flow sheet. Your new set of high impedance injectors are a match to the saturated injected signal produced by your Mustang’s OEM ECU. Each injector is covered by Fuel Injector Clinic’s one-year warranty if failure occurs from a manufacturing defect.

      Application. Fuel Injector Clinic’s 525cc Fuel Injector Set is designed for installation in 1999-2004 Cobra, 2005-2025 GT, Dark Horse and 2015-2022 GT350, GT500 Mustangs.
