PRODUCT FEATURES: The silencer adopts porous structure and S-shaped pipe. The porous design reduces air flow pressure, and the S-shaped pipe increases the sound resistance point and resistance to sound wave propagation to achieve the maximum efekt of noise reduction. The heating pipe is made of high quality stainless steel, and the silencer is made of aluminum alloy, which ma advantages of long service life, heat resistance, corrosion resistance, wear resistance and durability. Completely sealed, no need to worry about leakage. Easy to install, just remove the old or damaged part, attach the new do of the car and secure with latches and screws. The hose is suitable do additional air heating, petroleum parking heating, generator exhaust, additional vehicle air heating and additional diesel heating. 24 mm silencer replaces Eberspacher Airtronic D2, Airtronic D4, Airtronic D4S, D1LC, D1LC Compact, D3LC, D3LC Compact, D5LC.
