Fuel Injectors With Test Report

What Is a Test Report Certificate?

Every fuel injector in this collection ships with a serialized Test Report Certificate — a physical document that records the bench-test results for your specific unit before it leaves our facility. The certificate includes the measured flow rate at multiple pressure points, the high-pressure leak test result, and a spray pattern verification reading.

This level of documentation is typically reserved for OEM dealerships and professional rebuild shops. Aurus offers it as a standard inclusion for this premium tier so you can verify what you received matches what was promised — no trust required.

Why 1% Flow Matching Matters

Stock injectors from the factory are typically matched to within 3–5% of each other. Our test-report sets are matched to within 1%, which means your engine's ECU can maintain precise fuel trims across all cylinders. This is especially important for modern GDI engines and for any vehicle that has already had its injectors cleaned or replaced at different times.

All injectors in this collection carry Aurus's lifetime warranty. If you ever experience a flow rate deviation after installation, contact us with your certificate serial number for an immediate replacement.
