A dedicated PRORAM intake kit goes considerably further than replacing the filter element inside the factory airbox. These systems are designed around the individual vehicle and replace selected factory intake components with a freer-flowing induction path.

Many PRORAM kits combine a large pleated performance filter with a powder-coated heat shield designed to separate the filter from surrounding engine-bay heat. Depending on the application, revised pipework and other vehicle-specific components may also be included.

The objective is straightforward: reduce unnecessary intake restriction, increase induction sound and provide greater airflow capability for standard and modified engines.

Vehicle-specific engineering also removes much of the guesswork associated with building a universal intake. Mounting points, filter position and supplied components have already been designed around the intended platform.

PRORAM filters use a pleated synthetic nanofibre filtration medium designed to combine effective filtration with a large available surface area and high airflow capability.

The pleated construction is fundamentally different from the foam filtration used across much of the traditional Ramair range. Increasing the effective filter surface area allows PRORAM to package substantial filtration area into a compact cone-filter design.

Universal PRORAM filters are offered in different inlet diameters and physical sizes, making them suitable for custom intake fabrication, modified vehicles and applications where the original airbox has been removed.

Some versions also incorporate velocity-stack style inlet designs aimed at producing a smoother transition into the intake tract.

More Than Just Intake Noise

A performance intake is often noticed first because of the stronger induction sound, particularly on turbocharged engines. But the more important engineering objective is reducing unnecessary restriction between the outside air supply and the engine or turbocharger.

As engine output and airflow demand increase, the benefit of improving restrictive factory intake components can become more relevant.

Part of a Complete Performance Package

An intake system can be fitted to many otherwise standard vehicles, but it also makes sense as part of a broader performance package where higher airflow is required.

For tuned turbocharged vehicles, intake upgrades may be combined with ECU calibration, intercooling, turbo inlet improvements and exhaust modifications according to the requirements of the particular engine.

Choose a Vehicle-Specific Intake If...

• A PRORAM kit is available for your exact vehicle or engine.
• You want a complete, engineered installation rather than fabricating pipework yourself.
• You want stronger induction sound and a larger change from the factory intake.
• You want supplied heat shielding and mounting components where included.
• The vehicle has or may receive additional performance upgrades.

Choose a Universal Filter If...

• You are designing or modifying your own intake system.
• You know the required filter neck or inlet diameter.
• A dedicated kit is not available for your application.
• You need a particular filter size for a fabricated or motorsport installation.
• You already have suitable intake pipework and mounting arrangements.

Check the Inlet Diameter

Measure the outside diameter of the intake pipe, MAF housing or inlet the filter will mount to and match this to the specified internal diameter of the PRORAM filter neck.

Some PRORAM filters are designed to fit over a rigid inlet rather than directly onto a soft silicone hose, so check the mounting arrangement of the individual product before ordering.

Check the Available Space

Filter base diameter, overall length and surrounding clearance all matter. A larger filter may provide more filtration surface area, but it still needs to fit securely without contacting hot, moving or vibrating engine components.

Consider the entire intake layout, including cool-air supply and heat exposure, rather than selecting a filter solely because it has the largest possible dimensions.
