GMC Intake Manifold

Among the countless parts and components equipped in your vehicle, it is the engine that gets the most attention when car performance is concerned. Why? Well, it is because engine performance or the quality of an engine has a lot to do with the overall performance of a vehicle. However, the actual engine performance does not rely on the engine only. For an engine to perform at its best, it must be maintained at a particular operating temperature, so it needs to have an efficient cooling system. Maximum power production cannot be attained as well if the engine is not fed with the appropriate air/fuel mixture.

The intake manifold is the one that is responsible in doing so. The intake manifold is the mechanism that channels the air and fuel mixture from the throttle body to the valve ports. In other words, manifolds help control the amount of air and fuel that reaches the cylinders, directly affecting power generated by the engine. Basically, the more fuel and air that can be fed to the cylinders, the more power the engine produces. In addition, when we keep constant pressure on the accelerator pedal in order to remain at the steady speed, the intake manifold adjusts the amount of air to lessen the amount of fuel burnt, thus enhancing fuel efficiency.

Intake manifolds can generally be divided into two types: single-plane and dual-plane. Each type has its advantages depending on the application and the engine’s state of tune. For full-on high-performance use, most car enthusiasts choose a single-plane manifold. The advantage to a single-plane arrangement is that the manifold can be controlled to provide an almost straight shot to the combustion chamber, which is best at high rpms. On a dual-plane intake manifold, which is a better choice for street use, the plenum chamber is divided in half of the way up to the base plate of the carb. The advantage of this arrangement is that chamber volume is cut in half with respect to any given cylinder, which helps keep mixture velocity up, resulting in crisp throttle response and reducing the danger of pooling.

There will come a time when you will need to replace your GMC intake manifold because no matter how tough and durable your GMC intake manifolds are, they would still wear out. Intake manifold failures, particularly those with leaks, may result to poor engine performance, engine overheating, or worst, severe engine damage. The best place to go in looking for your replacement GMC intake manifolds is here at Parts Train. We offer a wide selection of GMC intake manifolds for every GMC model plus hundreds of car parts and accessories for other car makes as well.
