Frequently Asked Questions
How do I know if my GMC fuel injector is bad?
The most common symptoms are engine misfire (check engine light with codes P0300-P0308), rough idle, poor fuel economy, and hard starting. A fuel injector balance test can confirm which injector is faulty.
Can I replace just one fuel injector on my GMC?
Yes, but we recommend replacing all injectors on the same bank or as a complete set if the vehicle has high mileage. Mismatched flow rates between old and new injectors can cause idle issues.
Are Aurus injectors as good as OEM?
Aurus injectors meet or exceed OEM specifications. All injectors are flow tested and matched before shipping.
Do you offer a warranty on GMC fuel injectors?
Yes — all Aurus injectors come with a lifetime warranty against defects in materials and workmanship.
