Lester Urbina

Function Factory Performance High Performance Technician

With 7 years of experience in the automotive world, Lester Urbina has turned his childhood passion into a career that thrives on speed, precision, and innovation. From the age of 7, Lester was captivated by cars and dirt bikes, dreaming of the day he could work on high-performance machines. That dream became a reality when he pursued his automotive education at Oxnard College, graduating with flying colors in just two years.

But Lester didn’t stop there—his thirst for more led him to the Smog Institute Program, where he became a certified Smog Technician. However, his heart was always set on pushing the limits of performance. After completing HP Tuners’ intensive two-day course at The Tuning School, Lester knew he was destined to work at a performance shop where he could bring his tuning skills to life.

Today, at Function Factory Performance, Lester is living that dream, contributing to the world of vehicle modification and tuning. When he’s not at the shop, you’ll find him riding his dirt bike and exploring new places he never imagined he’d reach—always seeking the next adventure.
