cost of cleaning egr system on 2001 Acura TL

my mechanic says my egr is clogged and needs replacing and the orifaces and channels or tubes need to be cleaned. He wants $300 labor --says it will take 6 hrs. Is that about right???

Common problem on the Acura, labor rate to remove the intake manifold is a little over 2.5 hours add, .5 to remove EGR and .5 to clean passages is even generous time allotted. Not very difficult or high skill level repair.
