What is an Intake Manifold?
An intake manifold is a crucial component of an engine's air intake system. It distributes the air-fuel mixture to the engine's cylinders, ensuring optimal combustion. Upgrading to a performance intake manifold can improve airflow and increase engine power.
Why Should You Get an Intake Manifold Upgrade?
- Increased Horsepower and Torque: Performance intake manifolds improve airflow to the engine, increasing horsepower and torque.
- Enhanced Throttle Response: Better airflow can lead to quicker throttle response and improved acceleration.
- Optimized Air-Fuel Mixture: Upgraded intake manifolds ensure a more even distribution of the air-fuel mixture, improving combustion efficiency.
- Better Engine Performance: Improved airflow and combustion efficiency can lead to overall better engine performance.
How Does an Intake Manifold Work?
Factory intake manifolds are designed to balance performance and emissions, often compromising on airflow. Performance intake manifolds are engineered to optimize airflow, providing a more direct and efficient path to the engine's cylinders. Key components include:
- Plenum: The main chamber where the air-fuel mixture is distributed to the runners.
- Runners: Tubes that direct the air-fuel mixture from the plenum to the engine's cylinders.
- Throttle Body: Controls the amount of air entering the intake manifold.
Case Studies and Real-World Examples
A 2015 Chevrolet Camaro SS with an upgraded FAST LSX intake manifold demonstrated a 20 horsepower increase at the wheels and improved throttle response. Installation took about 4 hours with basic tools and a lift.
A 2018 Ford Mustang GT with a BOSS 302 intake manifold showed a 15-20 horsepower gain and enhanced mid-range torque. Users reported a more responsive throttle and improved acceleration. Installation took about 3 hours with basic tools and a lift.
