JDY Intake Manifold For VW MK7/MK8 GTI / Golf R / 8V/8Y Audi S3 EA888.3/.4

Unlock the true potential of your EA888 engine. Designed for high-boost applications and big-turbo builds, the JDY Billet Intake Manifold is the ultimate upgrade for enthusiasts who demand maximum airflow, structural integrity, and a premium engine bay aesthetic.

Product Overview

While the factory plastic manifold is prone to leaks and failure under high boost, the JDY-EA888-IM is engineered from a solid block of 6061-T6 Aluminum. Precision CNC-machined to perfection, this manifold provides the flow characteristics needed for Stage 3+ builds while ensuring rock-solid reliability.

Vehicle Fitment

• Audi A3/S3 (8V/8Y): 2.0T 2014–Present

• VW Golf GTI/R (MK7/MK7.5): 2.0T 2014–2020

• VW Golf GTI/R (MK8): 2.0T 2020–2024

• Fits both Gen 3 and Gen 4 EA888 engines.

Key Features & Improvements

1. Advanced Aerodynamics & Flow Dynamics

• Venturi Effect Runners: Our runners feature a tapered "wide-to-narrow" design, utilizing the Venturi effect to increase intake air velocity.

• Velocity Stack Entries: The plenum features curved "bell-mouth" inlets to ensure smooth, laminar airflow into each cylinder, eliminating turbulence and ensuring equal air distribution.

• Flow-Aligned CNC Path: Unlike standard machining, our tool paths follow the direction of airflow to minimize surface friction.

2. Built for Extreme Performance

• Billet 6061-T6 Construction: One-piece CNC machining offers superior strength over cast or welded alternatives, making it capable of handling high-pressure scenarios without risk of cracking.

• Thermal Management: Includes an 8mm thickened thermal gasket to insulate the manifold from cylinder head heat soak, keeping your intake temperatures (IATs) lower.

• Expanded Plenum Volume: Re-engineered internal volume provides the "lung capacity" needed for high-RPM power delivery.

• Runner flaps Delete : In orde rto reach maximum airflow capacity and reduce drag foraace as much as possible , JDY manifold deleted OEM runner flaps .

3. Integrated Solutions for Tuners

• Water-Methanol Ready: 4x pre-tapped 1/8 NPT ports located on the top of the runners for easy access and optimal atomization.

• Vacuum Reference Ports: 3x 1/8 NPT vacuum ports distributed across the plenum for clean routing of boost gauges, BOVs, or wastegate controllers.

• Engineered Clearance: Revised lower structure to provide 100% clearance for high-pressure fuel rails—no more interference or rubbing.

4. Hybrid Fueling & MPI Ready (For Gen 4 Support)
