Dongfeng VL Inlet intake pipe assembly 1109810-C4300

Designed to maximize air delivery efficiency, this intake pipe features a smooth, turbulence-free internal structure with carefully calibrated diameter transitions and gradual bends. The internal surface is polished to minimize air resistance, allowing a steady, high-volume airflow to the engine—critical for improving combustion efficiency, especially during high-load operation (e.g., heavy hauling or acceleration). The pipe’s length and volume are also tuned to match the Dongfeng VL’s engine displacement, reducing intake pulse interference and enhancing low-end torque—beneficial for fuel economy and overall driving responsiveness

The assembly is crafted from high-grade glass fiber-reinforced nylon (PA66+GF30), a material renowned for its exceptional heat resistance, mechanical strength, and chemical stability. It can withstand continuous exposure to high under-hood temperatures (up to 150°C) without warping, cracking, or deforming—preventing airflow restriction caused by material degradation. The material also exhibits strong resistance to automotive fluids (e.g., engine oil, coolant, and fuel vapors) and environmental contaminants (e.g., dust, dirt, and road salt), ensuring long-term structural integrity. Additionally, the pipe’s wall thickness is optimized to balance weight reduction and impact resistance, withstanding minor impacts (e.g., from tool bumps during maintenance) without damage

To maintain precise air-fuel ratios (critical for engine performance and emissions control), this intake pipe assembly features multi-layered sealing mechanisms at all connection points. It includes pre-installed, high-temperature-resistant EPDM (ethylene propylene diene monomer) rubber gaskets that form a tight seal between the pipe and the air filter housing/intake manifold—preventing unfiltered air from entering the engine (which causes carbon buildup and premature wear) and avoiding calibrated airflow loss (which reduces power and increases fuel consumption). The connection flanges are also precision-machined to ensure flat, even contact with mating components, while the integrated hose clamps (where applicable) provide secure, adjustable fastening to maintain seal integrity over time—even under engine vibration

Engineered for hassle-free replacement, this intake pipe assembly comes as a fully integrated unit with all necessary mounting hardware (brackets, clips, clamps) and pre-drilled holes that align with the Dongfeng VL’s factory mounting points. Installation requires no specialized tools—simply disconnect the old pipe from the air filter housing and intake manifold, remove its mounting brackets, then secure the new assembly using the provided hardware. The entire process takes 20-30 minutes (suitable for both professional mechanics and experienced DIY users). The pipe also retains compatibility with the vehicle’s original intake sensors (e.g., mass airflow sensor, intake air temperature sensor), with pre-positioned ports that match the sensor locations—ensuring the engine control unit (ECU) receives accurate data for optimal performance and emissions compliance
