BMW X5 Intake Manifolds

The purpose of your BMW X5's intake manifold is to evenly distribute the air coming into the engine to each intake port in the cylinder head(s), so that the perfect amount of air can mix with the perfect amount of gas. It ensures that there's enough air available when the valve opens for each intake stroke and that each cylinder gets the same amount of air as the others. If it's failing, you'll see misfiring, decreased power, acceleration, and fuel economy, plus overheating. Get your replacement here.
