what are the visual differances between a 6 liter air injected engine and a 6 liter with out air injection.
i just brought a H2 from the states on arival i notice the exuast manifold is not 100%, want to order a set of headers but they asked if it is an air injected motor.
how can i tell the difference, does any one have a photo of both motors so i can see quickly what it is i have.
