How Do Aftermarket Intake Manifolds Improve Your Mustang’s Performance?

The intake manifold, also called an inlet manifold, is a simple but vital component of your engine. The intake manifold is tasked with pulling fresh air into the engine, where it is evenly dispersed across each of the cylinders, combined with fuel, and combusted to create the power that drives that amazing engine. Most stock intake manifolds, even on muscle cars, are held back a little to aid other aspects of the car. But with an aftermarket Mustang intake manifold, you can maximize the amount of airflow that enters your engine. The more airflow, the more power the engine can generate as combustion occurs. And the more power generated, the more horsepower and torque you’ll feel when pressing on your right foot.

What to Think about Before Purchasing a 1999-2004 Mustang GT Intake Manifold

While intake manifolds are an aftermarket modification that we recommend to anyone who is looking to improve the performance of their Mustang, there are a few things that you should take note of before making this purchase. Most important is the fact that intake manifolds usually require recalibration upon installation. Without a recalibration, you’re basically just buying an intake manifold without getting any of the benefits. In order to see the power increase, you’ll almost surely need recalibration. It should also be noted that in some areas, certain intake manifolds can keep a car from being street legal. So make sure to research local laws, as well as the intake manifold that you’re considering purchasing.

What Are Plenums?

Plenums are simply the reservoir at the top of the intake manifold. The plenum is responsible for holding a supply of clean air, which the intake manifold then pulls from to send to the engine. As a basic rule of thumb, larger plenums can hold more air, which increases airflow and thus power. If you’re in the market for an aftermarket intake manifold for your 1999-2004 Mustang, then we’re here to help you out. Our sales techs are standing by to make sure you find the perfect intake manifold for your needs.
