Southern Performance just leveled up. We’ve added a full ASNU injector test bench with an integrated ultrasonic cleaner to our in‑house arsenal, so your injectors can get the same treatment your engine does. From port fuel to direct injection, we can now properly test, clean, and verify each injector before it goes back on your ride.That means better spray patterns, more consistent fuel delivery, and fewer “is it the tune or the injector?” headaches.

Drop your injectors off at SP Automotive / Southern Performance and let us put them on the new setup! Now 10% off for a limited time!
