JDY VW 7R/8R GTI EA888 Gen3/Gen4 Intake Manifold

Description

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, uncompromising reliability, and a premium engine bay appearance. Product Overview The factory plastic intake manifold can become a limitation on high-performance builds and is susceptible to cracking or leaking under elevated boost pressures. The JDY Billet Intake Manifold is precision CNC-machined from a solid block of 6061-T6 aluminum, delivering superior strength, improved airflow characteristics, and long-term durability for Stage 3+ and high-horsepower applications. Engineered using advanced CAD, CFD, and real-world testing, the JDY manifold provides optimized airflow distribution while maintaining OEM-level fitment and drivability. Vehicle Fitment Audi • Audi A3 2.0T (8V / 8Y) – 2014-Present • Audi S3 2.0T (8V / 8Y) – 2014-Present Volkswagen • VW Golf GTI (MK7 / MK7.5) – 2014-2020 • VW Golf R (MK7 / MK7.5) – 2014-2020 • VW Golf GTI (MK8) – 2020-Present • VW Golf R (MK8) – 2020-Present Compatible with all EA888 Gen 3 and EA888 Gen 4 engines. Key Features & Benefits 1. Advanced Airflow & Flow Dynamics Venturi-Optimized Runners The intake runners feature a carefully engineered tapered design that utilizes the Venturi effect to increase air velocity and improve cylinder filling efficiency. Integrated Velocity Stack Inlets Each runner entry features a bell-mouth velocity stack design to promote smooth, laminar airflow and minimize turbulence, ensuring consistent air distribution across all cylinders. Flow-Aligned CNC Machining Strategy Unlike conventional machining methods, the internal machining paths follow the natural direction of airflow, reducing surface friction and promoting maximum flow efficiency. 2. Built for Extreme Performance Billet 6061-T6 Aluminum Construction Manufactured from a single block of aerospace-grade 6061-T6 aluminum using full 5-axis CNC machining for exceptional strength and durability under extreme boost pressure. Enhanced Thermal Management Includes an 8mm thermal isolation gasket designed to reduce heat transfer from the cylinder head, helping lower intake air temperatures and improve consistency during demanding driving conditions. Increased Plenum Volume The optimized plenum design increases available air volume, supporting improved cylinder filling and enhanced high-RPM power delivery. Runner Flap Delete To maximize airflow capacity and eliminate unnecessary airflow restrictions, the JDY intake manifold removes the factory runner flap system. 3. Integrated Solutions for Tuners Water-Methanol Injection Ready Four pre-machined 1/8" NPT ports are located on top of the runners, providing ideal placement for water-methanol injection nozzles. Vacuum Reference Ports Three integrated 1/8" NPT vacuum ports allow clean installation of: • Boost gauges • Blow-off valves (BOV) • Wastegate controllers • Additional vacuum accessories Improved Fuel Rail Clearance The lower manifold structure has been redesigned to provide complete clearance for upgraded high-pressure fuel rails, eliminating interference issues commonly found on modified vehicles. 4. MPI & Hybrid Fueling Ready Port Injection Integration Many EA888 Gen 3 and Gen 4 engines were delivered without Port Fuel Injection (MPI). The JDY manifold restores MPI capability, providing the additional fueling capacity required for high-horsepower applications running ethanol blends, race fuel, or large turbochargers. Included AN6 Billet Fuel Rail Every manifold includes a CNC-machined high-flow AN6 billet fuel rail. Flexible Fuel System Configuration Recirculating Setup The fuel rail features AN6 ORB (O-Ring Boss) ports on both ends, allowing the use of custom braided fuel lines and aftermarket fuel pressure regulators. OEM Fuel Line Compatibility A custom barb adapter is included and connects directly to the factory fuel line connector, providing a simple plug-and-play solution for vehicles retaining the OEM fuel supply system. Optimized Injector Positioning The manifold and fuel rail are engineered together to ensure proper injector alignment, ideal spray targeting, and reliable sealing under high fuel pressure. 5. Appearance & Installation Diamond-Cut Exterior Design The aggressive diamond-cut exterior styling provides a premium appearance while maintaining the performance-focused aesthetics expected from a modern billet intake manifold. OEM Integration Designed to retain: • Factory PCV functionality • OEM throttle body location • Factory sensor compatibility for a true bolt-on installation experience. Included Installation Hardware Each kit includes: • Custom coolant hose kit • Hose clamps • Mounting brackets • 8mm thermal gasket The supplied coolant hose kit replaces bulky factory coolant lines, creating additional clearance for the larger plenum design.
