PERFECT FLOW. ZERO COMPROMISE.
The "Hidden Hardware" Upgrade for MCD.
100% Stock Compatibility. 7075-T6 Precision. Zero Turbulence.
The stock MCD air filter system is brilliant—we didn't change how it fits. We optimized how it flows.
Standard velocity stacks have one flaw: mounting screws inside the air path create turbulence. The AKILL Two-Piece Velocity Stack eliminates this. By hiding the hardware, we create a perfectly smooth air tunnel while retaining full compatibility with your original MCD air filter cage and foam.
⚡ The Flow Dynamic Difference
Turbulent Airflow
Excellent 7075 material, but the exposed screw heads create "wake turbulence" right before the engine intake.
Laminar Flow
We separated the stack to hide the screws. The result is a mirror-smooth tunnel for maximum air velocity.
⚙️ Engineering Highlights
🚫 Hidden Hardware Technology
The Logic: You want air to move fast. Obstacles slow air down.
The Solution: Our 2-piece design allows the base to be bolted down flush, then the funnel screws on top. This removes all obstructions from the air path.
✅ 100% OEM Compatibility
This is a direct replacement. It works perfectly with your existing MCD Air Filter Cage, Foam, and L-Tube. You keep the stock quick-release convenience, but gain performance.
💎 Material Standard: 7075-T6 Aluminum
We matched the OEM's high standard. Machined from Aerospace 7075-T6, this stack offers the same extreme durability and heat resistance as the original factory part.

🛠️ Assembly Tip
We recommend applying a light coat of grease on the O-ring between the two pieces. This ensures a perfect air-tight seal and allows for smooth assembly.
