A vehicle is equipped with a lot of different parts but it is usually the engine
that gets the most attention when vehicle performance is concerned. Indeed, the
performance of an engine has a lot to do with the overall performance of a vehicle.
Vehicles with large, powerful and technologically advanced engine are often expected
to perform better than those with age old and small engines.
While it is true that engine performance is critical to the performance of a
vehicle as a whole, the actual engine performance does not rely on the engine
alone. For an engine to perform at its best, it must be maintained at a particular
operating temperature, thus it must also be equipped with an efficient cooling
system. Utmost power production is also unachievable if the engine is not fed
with the proper air/fuel mixture, making both the vehicle's fuel distribution
system and its air intake system equally significant for optimum engine performance.
Then, of course, there is the lowly intake manifold that allows this proper air/fuel
mixture to reach each and every cylinder of the vehicle's engine.
The intake manifold is a system of passages that delivers the fuel/air mixture
from the carburetor (for older vehicles) or from the throttle body (for modern
vehicles) to the intake valves or ports of the engine's cylinders. Typical intake
manifold configurations include a plenum, which is a chamber in the manifold used
to distribute the intake charge evenly to the intake runners. The intake runners,
on the other hand, refer to the individual tubes that lead to the intake valves
of the engine's cylinder heads.
Now, the intake manifold may appear like a very simple system that cannot possibly
improve or limit the performance of the vehicle's engine. The design of the intake
manifold, however, is proven to affect the actual performance of the engine. Intake
manifolds must be designed in such a way that they would not limit the flow of
the air/fuel mixture to the vehicle's engine. The air/fuel mixture that passes
through the manifold must also be delivered in equal strength and quality to each
cylinder to ensure smooth and optimum engine performance.
The superior performance of Chevrolet vehicles, regardless of the type of engine
they are equipped with, just proves that these vehicles are equipped with cleverly
designed and high quality intake manifolds. But even the best Chevrolet intake
manifold would wear out in due time. Sometimes, damages in inlet manifolds that
may cause leaks are also inevitable. And just as the design of the intake manifold
can affect the engine's performance, damages in it may also reduce engine output.
Good thing, there are online auto parts sources like Parts Train that can provide
you with a high quality Chevy replacement intake manifold whenever you need it.
