Frequently asked questions about Infiniti Qx4 fuel injectors
How many fuel injectors does a Infiniti Qx4 need?
Most Infiniti Qx4 engines use 6 fuel injectors — one per cylinder. We sell both single-injector replacements and complete sets of 6. Check the engine description on each product card to confirm the configuration matches your vehicle.
What's the warranty on Infiniti Qx4 fuel injectors from Aurus?
All Infiniti Qx4 fuel injectors we ship — both new Aurus and remanufactured OEM — come with a lifetime warranty against defects, plus a 30-day no-hassle return window.
What's the difference between OEM Aurus and OEM Remanufactured injectors for the Infiniti Qx4?
For this Infiniti Qx4 we currently stock OEM Aurus New. New OEM Aurus injectors are USA-assembled with premium OEM-grade components from Bosch, Continental and other top-tier suppliers — direct OE-equivalent fit. OEM Remanufactured units are genuine OEM cores fully restored and flow-tested at rated PSI on Bosch EPS 815 equipment.
Will these fit my specific Infiniti Qx4?
