I just recently purchased a 2002 Dodge Ram 4 Door 4x4 with a 5.9. The truck has minor performance upgrades such as a K&Nair filter, maganaflow exhaust. The previous owner did several appearance upgrades also. My friend noticed that the injectors are red I've had several 1st and 2nd gen rams and a couple of prowlers and all had plain black injectors are these on my 02 high flow injectors or are they all red on this model. Thanks in advance...Joe
