Intake Manifold Repair $1200 on 1999 Honda Passport

I've been told that Honda sells intake manifold as a package and it costs around $1200 for parts & labor? Is this possible or a scam?

sounds high.
new manifold, lower, 455
gasket 25
labor 2.2 hours

still a ways away from 1200. was there something else in the estimate??

Check Engine Light code P0171 and PO174. Found leak in Vacuum control valve, intake manifold gaskets. They say that they have to replace the entire intake manifold, b/c Honda doesn't sell just the parts. Estimate for parts & labor $1200.
Then find a good independent repair shop.
What is the problem with the Passport?
