    Default I have a question about EGR's

    So why does the 86 to 93 have that spacer plate that has coolant hose going to it and the 94-95 does not? It might be a dumb question but im working on my first fuel injected motor so im trying to learn the systems

    It has to do with the difference in where they source the exhaust gas for EGR from. On 86-93 the exhaust gas comes from the cylinder heads and up through the intake manifold to the EGR valve. On 94-95 the exhaust gas is sourced from the passenger side exhaust header and runs up a pipe directly into the EGR valve.
