DeatschWerks offers top feed conversion fuel rails for converting side-feed applications to top-feed. Many performance vehicles manufactured between the years 1991 and 2006 came from the factory with side feed injectors. Modern top-feed injectors are easier to tune, less expensive, and flow more fuel than the side-feed alternatives. These conversion kits include injectors ranging from 750cc to 2200cc and are engineered as a system where the injector, rails, and mounting hardware all work together to integrate flawlessly into the OE manifold and mounting points. DW rails are offered in multiple kit options to meet your needs, order the kit to fit your application.
