This is a set of 5 new SMP fuel injectors that would fit Chevy Buick Pontiac Olds 2.4 I4 engines from 1996-1999. These are a few interchangeable part numbers like GB REMANUFACTURING 83211146 and an OE/OEM part number of GM 17122264. These fuel injectors are manufactured in Japan and are made exclusively for gasoline engines. They are not compatible with diesel engines obviously.
