This genuine parts list and diagram shows the Air Inlet assembly for a 1990 M3 Base 4 cylinder 2.3 liter engine. All of these M3 Base Engine parts ship directly to you from our dealership parts department.
After air is sucked into the air intake, and is filtered by the engine air filter, it passes through the air inlet tube and reaches the engine's intake manifold. This hose is made of rubber, and due to the extreme heat in your engine bay, can dry out and cracnk or even split, causing air to leak out which can cause a reduction in engine performance and fuel economy.
No known discontinued parts in this assembly. If you believe a part is discontinued, feel free to notify/contact us
