Construction & Design:
The Delta Force intake system is built with premium materials to withstand the rigors of both on- and off-road use. The intake tube is crafted from Cross-Linked Polyethylene (XLPE), known for its strength, heat resistance, and smooth internal surface that promotes efficient airflow. The black anodized aluminum fittings not only enhance durability but also provide a clean, custom appearance.
Reinforced silicone couplers ensure a tight seal and flexibility to accommodate engine movement and vibrations. Stainless steel hardware is used throughout to prevent corrosion and maintain a secure assembly over time. The included air dam is powder-coated black to resist chipping and corrosion, while its design helps direct cooler air into the intake for improved performance.
