This A-Premium kit contains eight matched 4-hole injectors manufactured to fit a long list of GM platforms from model years roughly 1999–2007, and includes the part references commonly used for cross-checking compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines do these injectors fit?\u003c\/h3\u003e\n\u003cp\u003eThese injectors are designed for a wide range of GM vehicles equipped with 4.8L, 5.3L or 6.0L gasoline V8 engines across Chevrolet, GMC, Buick, Cadillac and related platforms.
