Industrial Injection has supplied the diesel performance industry with the best high performance fuel injection components and turbochargers on the market for over 25 years. Owner/founder Brady Williams started Industrial Injection as a one man show, primarily as an agricultural and industrial fuel shop servicing construction, agricultural, mining equipment and over the road truck engines.
From the beginning their focus was on helping farmers, truckers and miners with horse power gains, fuel economy and reduced emissions. When Ford, Dodge and GM decided to power pickup trucks with diesel engines Industrial was quick to recognize the needs that would come and adapted their business model to service this new and growing diesel market segment. Today Industrial Injection utilizes their extensive experience in conjunction with advanced technology and a strong desire to lead diesel innovation to create diesel performance products for true diesel enthusiasts.
