ECS Tuning Billet Aluminum 1.8T Fuel Injector Cup - Priced Each

Constructed from heat-sensitive plastic, your factory 1.8T fuel injector cups are prone to self-destruction. After years of constant exposure to engine heat, vibration, and chemical-laden fuel residue, cracks will form in the seat of the insert and create a multitude of issues. Boost and fuel leaks will eventually prompt a lean running condition, a rough idle, and multiple diagnostic trouble codes.

With these issues in mind, our engineering team set out to create an everlasting, performance-minded replacement for the factory insert. The result is a precision-machined piece crafted from 6061-T6 billet aluminum—a material selected for its excellent strength, durability, and overall resistance to fatigue. Unlike the brittle OE plastic inserts, our billet cups are built to last under extreme stress, ensuring your injectors remain perfectly seated and aligned at all times.

To protect the surface, each injector cup is finished with type-II satin silver anodization. This adds a durable layer of corrosion and chemical resistance, ideal for withstanding fuel and oil vapor exposure when installed inside the intake manifold. Precision tolerances and a threaded design provide a secure, leak-proof installation that eliminates boost leaks and injector misalignment.

Whether you're shopping for a durable replacement for your worn plastic cups or vetting a performance upgrade, choose our Billet Aluminum Injector Cups for your 1.8T to ensure long-lasting durability!

DESIGN

• Precision-machined to match the exact tolerances and dimensions of the OEM Fuel Injector Insert
• Manufactured from 6061-T6 billet aluminum for increased durability
• 20mm internal hex drive structure provides trouble-free installation
• Type-II hard-coat anodized ensures lasting corrosion resistance

INSTALLATION & SUPPORT

Our Billet Aluminum Injector Cups install the same as your factory plastic inserts, providing an easy, stress-free upgrade. To ensure a leak-free seal, we recommend purchasing Loctite® #565 Thread Sealant (ES#2770778) and applying it to the threaded portion during installation. Additionally, we suggest a 20mm Allen Key to aid in the installation process (ES#4912390).

PRODUCT DEVELOPMENT

Our 1.8T Billet Aluminum Injector Cups were tested and quality inspected by our research and development team at our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.
