What It Helps Address

• Hard starting caused by inconsistent fuel delivery
• Rough idle from poor injector spray pattern
• Misfire conditions related to injector performance
• Fuel trim issues tied to uneven flow rate
• Driveability problems from worn or contaminated injectors

Installation Notes and Tips

• Confirm vehicle fitment by year, make, and model before installation.
• Follow the included fuel injector replacement instructions where provided.
• For 2013 Nissan Altima applications, replace the fuel filter when the injector is replaced, where applicable, per Technical Bulletin TB-0119-EFS.
• For 2019-2023 Nissan Maxima and 2020-2023 Nissan Murano, replacement of the fuel filter is recommended when the injector is replaced, where applicable.
• Inspect seals and mating surfaces during service to help prevent fuel leaks.

Quality Assurance

Each injector is remanufactured and tested to meet or exceed OE specifications for the covered performance checks. The process includes new external seals and o-rings, along with verification of fit and function before release.
