Why do I need a heat shield on my intake manifold?
Intake heat shield. The purpose of the heat shield is to protect the bottom of the intake manifold from hot oil being splashed up onto it. This wasn’t to keep the intake cooler, it was to keep the splashed oil from carbonizing on the hot exhaust heat crossover that runs beneath the plenum to provide carb heat.
How much does it cost to replace an intake manifold?
You can expect a total cost of 300$ to 1100$ for an intake manifold replacement. This cost differs a lot depending on the car engine and car model you have. It also depends if you are looking for OEM or aftermarket parts.
Why is the intake manifold at the end of the engine?
In older cars, the carburetor injected fuel before the intake manifold, and for these engines, the intake manifold needed to spread this fuel evenly. Newer cars inject fuel at the end of the intake manifold with fuel injectors, and the even spread is not as important anymore as before.
Can a 72 degree intake manifold be made?
The early intake can be made to fit later 72 degree heads by slotting the bolt holes and fabricating (or buying) shims to correct the angles (same with using the later intake (both TBI and TPI intakes from F-bodies (Camaro/Firebird) with the early cylinder heads and 87-91 Corvette aluminum heads).

What are the symptoms of intake manifold problems?
1. Engine misfires and decrease in power, acceleration, and fuel economy. One of the most common symptoms of an issue with intake manifold gaskets is engine performance issues.
What is the role of the intake manifold gaskets?
The intake manifold gaskets are responsible for sealing the intake manifold against the cylinder head(s). Apart from sealing engine vacuum, certain designs will also seal engine coolant.
How do you remove an intake manifold on a BMW?
Remove the ten 11mm intake manifold nuts (green arrows). Use a magnet to extract the nuts once they are removed. With help from a friend, lift the intake manifold up to remove it, untangling wires and hoses as you both lift it. With the intake manifold removed you can now replace the intake manifold gaskets (green arrows).
