Injen

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 wavered from their commitment to innovate and deliver products that solve for the increasingly complex nature of vehicles brought to market.

Nearly three decades later – with several more patents developed and applied to several thousand new products - the Injen brand has become a household name among enthusiasts who demand high quality, dyno-proven solutions for their vehicles.

As we continue to grow – expanding into new market segments and to further regions of the world – the Injen team holds steadfast to the vision of our founder with innovation that transforms the look and performance of your vehicle.
