This is a set of 6 individual Engine Identification numbers for your car or truck. These are made of a durable hard plastic material that have a self stick backing. These emblems have a beautiful gloss black finish that looks great on any color vehicle. Each number measures 1" tall and 1 1/2" in length. These are 1/8" thick. Since these have a self stick backing installation is a snap as they require no drilling. You can space the numbers as close or as far apart as you desire. They would look great on the fenders, hood scoop, intake plenum or car show display.
