Frequently asked questions about Buick fuel injectors
How many fuel injectors does a Buick need?
Fuel injector count depends on the engine — typically one injector per cylinder. We sell both single-injector replacements and complete OEM-matched sets. Pick the year and engine above to see the exact set sizes that fit your Buick.
What's the warranty on Buick fuel injectors from Aurus?
All Buick 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 Buick?
For this Buick we currently stock OEM Aurus New and OEM Remanufactured. 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 Buick?
Use the year and engine selectors above to filter to your exact fitment. We only display products whose verified compatibility data matches your vehicle — no guesswork.
