Imagine trying to run a marathon, but every breath you take in is through a straw. That’s what the factory intake is doing to your car. Upgrading to a cold air intake allows for more air to come in. The intake then cools that air allowing it to expand faster and in-turn increase horsepower. The Magnum Force Stage 2 Si Intake System for the N55 BMW Turbo cars, take the factory pan setting and replaces it with a cone filter that increases by 300 cfi on average. Think about it like taking a deep breath in with your mouth open rather than taking a deep breath through a straw. You’re not going to be able to run long distance at high speeds if all the air you’re taking in is coming through a straw-like hole. Do your car a favor, take out the straw, and let your car intake air with an open mouth.
aFe has specialized in BMW parts for years, their new Magnum Force Stage 2 Si Intake System is made specifically to boost your hp by allowing more air to be cooled on intake.
