Selecting a Port Injection System: Plate vs Manifold Style

Plate Style Port Injection

In plate style port injection, a fuel distribution plate with multiple fuel injectors is placed between the intake manifold and the cylinder head.

Simplicity: Plate style port injection is relatively easy to install and requires fewer modifications to the intake manifold.
Cost-effectiveness: It is usually more affordable compared to manifold style port injection systems.
Hidden injector/fuel rail setup: This can be advantageous if you prefer a cleaner, stealthier appearance under the hood.

Installing a plate style port injection system can impact the fitment of the engine cover. The presence of the fuel distribution plate and injectors may prevent the engine cover from being reinstalled properly.
The hidden injector/fuel rail configuration can make it challenging to visually detect for fuel leaks. Regular inspection and diligent maintenance become even more important to ensure there are no leaks compromising the fuel system's integrity.

In manifold style port injection, individual fuel injectors are installed directly into each intake runner of the intake manifold.

Potential for higher power: The improved fuel distribution and precise tuning capabilities of manifold style port injection can potentially lead to higher power outputs.
The installation of an aftermarket manifold style port injection system can provide a more visually modified and aggressive appearance to the engine bay.
Depending on the specific design, an aftermarket manifold style port injection system may offer improved airflow and cooling characteristics.
An advantage of manifold style port injection is its direct fitment without requiring modifications to the engine cover or relocation of the charge pipe. This can save time and effort during installation, as the system is designed to fit seamlessly into the existing engine bay setup.

Increased complexity: Replacing the manifold may require more labor for installation.
Higher cost: The added complexity and manufacturing process contribute to higher costs compared to plate style port injection systems.

Choose the port injection system that will work best for your desired mods and gains for your car.
