* The nature of the problem: A simple gasket leak might cost only a few hundred dollars for parts and labor, while a cracked manifold requiring replacement could easily run into the thousands. A warped manifold is somewhere in between.
* Labor rates: Mechanic labor rates differ significantly by location and shop. Independent shops are generally cheaper than dealerships.
* Parts cost: The price of a new or remanufactured intake manifold varies depending on the supplier and whether you opt for a genuine GM part or an aftermarket one.
* Additional repairs: Often, problems with the intake manifold reveal other issues that need addressing at the same time (e.g., vacuum leaks, sensor problems). This will add to the overall expense.
In short: You could potentially get away with a relatively inexpensive repair (under $500), but it's also possible to face a bill of $1000 or more, especially if the manifold needs replacing and other related problems are discovered.
It's best to get a diagnostic check from a trusted mechanic to determine the exact problem and receive an accurate estimate before proceeding with any repairs. Trying to get a price range online without a proper diagnosis is unreliable.
