FAQ
Are these injectors streetable?At 350% over, they are intended for competition builds. Expect heavy fueling needs, smoke potential without adequate air, and the need for custom tuning.
Do I need a bigger CP3 and lift pump?Yes. A high-output CP3 (or dual fuelers) and a quality lift pump/filtration system are strongly recommended to maintain rail pressure and protect the injectors.
Will these fit late 2004–2007 trucks?No. This set is for early 2003–2004 5.9L CR engines. Late-2004.5–2007 use a different injector family.
Are the injectors matched?Yes. Sets are flow-matched for consistency cylinder-to-cylinder.
