Air Injection Block Off Plate Aluminum for VW Audi MK4 B5 1.8T
Eliminate premature second‑air injection system failures or excessive under‑hood heat with this precision‑machined aluminum block off plate, specifically engineered for 1.8 turbocharged engines across the Volkswagen and Audi MK4 and B5 platforms. Manufactured from durable aluminum alloy, this direct‑fit deletion component replaces the factory combi valve assembly, streamlining your intake routing and removing a frequent source of vacuum leaks and oil vapor contamination. Designed for 1998 through 2006 applications, it delivers a clean drop‑in solution that enhances engine response while keeping your engine bay neat and efficient.
Benefits & Practical Tips
•Durability: Solid aluminum construction reliably outlasts fragile plastic or cast‑iron OEM valves that routinely crack or seize.
•Performance Cleanup: Deleting the secondary air injection combi valve improves airflow consistency and simplifies routine diagnostics when paired with stage 1 or 2 power mods.
•Maintenance Advice: The unit mounts directly using existing factory fasteners. Remove the original valve, position this blanking plate with the included O‑ring gasket, and torque the bolts evenly. Clean mating flanges thoroughly before seating to guarantee a leak‑free bond.

Important Reminders
This deletion kit is engineered strictly for unrestricted, off‑road, or competition use and will not meet standard highway emissions requirements in most regions. Because no instructional manual is packaged with the part, we strongly recommend professional fabrication shop installation to prevent incorrect torque sequencing or clearance conflicts. Verify your vehicle’s existing combi valve layout and accessory routing before purchase.
