About Smog Brothers HDI/M.

Owner Amir Elfarra began his journey in the emissions industry when he was just 10 years old. He had the opportunity to learn alongside his uncle, who has spent his entire career in the smog industry and currently owns and operates his own shop in Fallbrook, CA. From a young age, Amir was taught that doing the job right, caring for customers, and taking pride in his work are the qualities that not only set a business apart but also build lasting relationships. These are the values he carries with him during every test.

​

Amir started Smog Brothers HDI/M with two goals in mind: to build long-lasting relationships with customers and to make heavy-duty diesel emissions testing as convenient, reliable, and stress-free as possible. Instead of customers having to take time out of their day to visit a testing facility, Smog Brothers HDI/M brings professional mobile testing directly to their location. Whether you’re an RV owner, owner-operator, fleet manager, or anyone operating heavy-duty diesel vehicles, Smog Brothers HDI/M is here to help keep your vehicles compliant while minimizing downtime.

​

Amir believes every customer deserves honest communication, dependable service, and attention to detail. Every inspection is performed using properly maintained and calibrated equipment and in compliance with California’s heavy-duty diesel emissions testing requirements, helping ensure accurate and reliable results customers can trust.

​

For Amir, this business is about more than just passing inspections. It’s about building lasting relationships, earning trust through quality work, and providing the kind of service that keeps customers coming back and recommending Smog Brothers HDI/M to others.
