In 1988, a young entrepreneur named Ron Delgado was working late into the evening – trying to find a better way to polish products for his family “job shop” business. At the time, most machines only polished along flat surfaces. But when Ron had the idea for a multi-axis machine – which could polish better and faster than anything he had used before - he was determined to make it a reality. What began as a mission to perfect the art of polishing soon grew into a full-fledged quest to develop industry-changing design and manufacturing solutions. And, in 1991 – as the demand for high quality aftermarket air induction products began to reach scale – Ron knew he had found an opportunity to make his mark on an industry he loved. Launching Injen – with a pioneering patent that allowed enthusiasts to achieve better performance from their vehicles without annoying “Check Engine Lights” (CEL’s) – Ron and his team have never waivered from their commitment to innovate and deliver products that solve for the increasingly complex nature of vehicles brought to market.
