Since that time, the company has made it a point to stay at the forefront of performance technology, continually setting new standards for quality and improving their engineering and manufacturing capabilities. This enables Injen to regularly introduce new, cutting edge products to market and has required the company to continually expand to meet the demand for those products. Today, Injen continues to set the industry benchmark for innovation, styling and technology.
