For over a decade Injen Technology Co. Ltd and their sister company have played a major role in the design and development of air intake systems. Injen Technology is based out of California in the same city and just a few miles away from the famous Pomona Winter Nationals Top Fuel Raceway. Injen Technology's history is a classic success story of a small manufacturing company turned industry leader of aftermarket performance products.
What most people do not know is that Injen's sister company, RD Metal Works established in 1981, was actually designing and manufacturing air intake kits for leading air filter and intake manufacturers since the mid 1990's. Absorbing the experience, design capabilities and quality standards of RD Metal Works, Injen Technology was formed. Injen Technology has made it a point to stay at the forefront of performance technology making only the best air intake one can envision.
