What is an Intake Manifold?

An intake manifold is a component in an engine that distributes air and fuel to the cylinders. It is connected to the engine’s air intake system and is responsible for delivering the necessary amount of air and fuel mixture to the engine’s combustion chamber.

Why are Racing Intake Manifolds Important?

Racing intake manifolds are designed to provide maximum airflow to the engine’s combustion chamber. This increased airflow results in improved engine performance, which is essential for racing applications.

Types of Racing Intake Manifolds

There are several types of racing intake manifolds available in the market. The most common types are single plane and dual plane intake manifolds. Single plane intake manifolds are designed for high RPM applications, while dual plane intake manifolds are designed for low to mid RPM applications.

Benefits of Racing Intake Manifolds

The benefits of racing intake manifolds are numerous. They can improve engine performance, increase horsepower and torque, and provide better throttle response. Racing intake manifolds also have a better flow rate than stock intake manifolds, which can result in better fuel economy.

Choosing the Right Intake Manifold

Choosing the right racing intake manifold for your vehicle can be a daunting task. There are several factors to consider, including the type of engine, the intended use of the vehicle, and the budget. It is important to do your research and consult with a professional to ensure you select the right intake manifold for your needs.

Installation and Maintenance

Installation of a racing intake manifold can be a complex process, and it is recommended that it be done by a professional. Proper maintenance of the intake manifold is also important to ensure optimal performance. Regular cleaning and inspection of the intake manifold can help keep it in good condition.

Cost of Racing Intake Manifolds

Racing intake manifolds can range in price from $120 to several thousand dollars. The cost will depend on the brand, type, and quality of the intake manifold. It is important to consider the overall value and benefits of the intake manifold when making a purchase decision.

Top Brands of Racing Intake Manifolds

Some of the top brands of racing intake manifolds include Edelbrock, Holley, and Weiand. These brands are known for their high-quality products and exceptional performance.


Racing intake manifolds are an essential component for anyone involved in automotive racing. They can provide a significant increase in engine performance and improve overall vehicle performance. It is important to choose the right intake manifold for your needs and to ensure proper installation and maintenance.
