Upgrade the airflow, turbo response, and induction sound of your Volkswagen MK8 Golf GTI with the ARM MK8 GTI 4-Inch Intake. Specifically engineered for the EA888 Gen 4 2.0T Evo4 engine, this high-flow intake system is designed to eliminate restrictive factory intake components and provide a significantly larger, more efficient path for air to reach the turbocharger.

Featuring a massive 4-inch intake design, a high-capacity inverted air filter, reinforced silicone intake hose, integrated aluminum heat shielding, and a clear heat shield cover, the ARM MK8 GTI Intake is built to support everything from stock and tuned vehicles to hybrid and upgraded turbocharger applications.

The increased intake volume helps the EA888 Gen 4 breathe more efficiently, promoting improved turbo spool, increased airflow, and enhanced throttle response. It also dramatically increases the audible character of the turbocharger, allowing you to hear more turbo spool under acceleration and a pronounced air-release sound when lifting off the throttle.

4-Inch High-Flow Intake Design

At the heart of the ARM MK8 GTI Intake is its massive 4-inch inlet size at the air filter. This large-diameter design is engineered to reduce airflow restrictions and provide the volume of air required by high-performance EA888 Gen 4 applications.

A rigid 4-inch aluminum intake pipe connects the air filter to the reinforced intake hose while maintaining the large internal diameter through the heat-shielded section. The intake hose then transitions to 3 inches at the turbo inlet, allowing it to connect directly to the ARM MK8 GTI Turbo Inlet.

For vehicles retaining the OEM turbo inlet, an included adapter ring provides a direct and seamless connection, making the intake suitable for both OEM and upgraded turbo inlet configurations.

Reinforced Silicone Intake Hose

The ARM MK8 GTI Intake utilizes a 6-layer reinforced high-temperature silicone intake hose engineered to maintain its shape and structural integrity under demanding driving conditions.

The large-diameter hose is designed to provide smooth, unrestricted airflow while resisting deformation during high-load operation. Its 3-inch turbo-side connection is optimized for compatibility with the ARM MK8 GTI Turbo Inlet while also supporting the included OEM turbo inlet adapter.

Integrated Aluminum Heat Shield

The air filter is enclosed within a laser-etched aluminum heat shield finished in wrinkle black. The heat shield helps isolate the intake filter from hot engine-bay air, helping maintain cooler intake temperatures and reducing the potential for heat soak.

The system utilizes the OEM fresh-air snorkel to direct outside air toward the filter, providing a continuous supply of cooler air.

A clear heat shield cover is included as standard. The cover allows the high-flow air filter to remain visible while sealing the upper portion of the heat shield for additional protection against engine-bay heat.

For drivers who prefer to operate the intake without the clear cover, weather stripping is included to create a seal around the top of the heat shield and help prevent hot engine-bay air from entering the intake system.

High-Capacity Inverted Air Filter

The ARM MK8 GTI Intake features a specially designed inverted air filter that maximizes available filtration surface area.

Combined with its massive 5.5-inch filter base, the inverted filter provides more than 300 cubic inches of filter surface area. This high-capacity design is engineered to provide ample airflow for both stock and high-power applications, helping ensure the intake system does not become an airflow limitation as engine power increases.

Integrated SAI Filter System

Included with the intake is a CNC-machined aluminum SAI filter adapter designed to integrate directly with the factory secondary air intake system.

The SAI filter is positioned inside the intake heat shield, allowing it to draw air from the cooler, protected area within the airbox rather than directly from the hotter engine bay.

Enhanced Turbo & Intake Sound

In addition to improving airflow, the ARM MK8 GTI 4-Inch Intake significantly enhances the sound characteristics of the EA888 Gen 4 2.0T.

Drivers can expect a more pronounced turbo spool sound during acceleration, along with a noticeably louder air-release sound when lifting off the throttle. This makes the intake an excellent upgrade for enthusiasts looking to enhance both the performance potential and driving experience of their MK8 GTI.

Compatibility & Turbo Inlet Options

The ARM MK8 GTI Intake is designed to work with both the ARM MK8 GTI Turbo Inlet and the OEM turbo inlet.

• ARM Turbo Inlet: Direct connection for a larger, unrestricted induction path.
• OEM Turbo Inlet: Included adapter ring provides compatibility with the factory turbo inlet.

For maximum airflow potential, the intake can be paired with the ARM MK8 GTI Turbo Inlet to create a larger and more efficient induction path from the air filter to the turbocharger.

Installation

The ARM MK8 GTI Intake is designed for a straightforward installation and can typically be installed in approximately 45 minutes using standard tools and the included hardware.

No major modifications to the vehicle are required for installation.
