A lot of places bill shop labor around the same as the retail cost of the parts being replaced. That being said, I assume you are talking about the lower portion of the intake manifold. You should be able to go onto car-part.com and find one from a similar model year 3.5L trooper or honda passport and I think there was an acura suv that used the same engine too. Our engine code is 6VE1 so look for that when you're searching. Local auto parts places like pick and pull are likely to have them. What exactly is wrong with it that it needs replacing? If it's cracked or leaking, a good shop should be able to repair it themselves.
