The cummins ISX engine replaced the popular N14 model when it was discontinued in 2000. The 6-cylinder, inline engine was equipped with the new Interact System of electronics controls, making it compliant with the 2002 EPA requirements. A few years later, the QSX engine was introduced, upgraded with the new Quantum System controls.
We carry a large assortment of new and remanufactured parts for ISX and QSX diesel engines.
