aFe Power Magnum Force Stage-2Si Cold Air Intake - BMW E9x 3-Series (325i/328i/330i N52 & N53)

Unlock the true sound and performance of your naturally aspirated inline-six.

The original factory intake system is restrictive and muffles the glorious intake sound of the BMW 3.0L 6-cylinder engine. The aFe Power Magnum Force Stage-2Si Cold Air Intake is engineered to eliminate these restrictions, forcing a massive volume of cool, dense air straight into your engine. The result? A noticeable gain in horsepower, sharper throttle response, and a deep induction roar when you step on the gas.

Why the aFe Stage-2Si is the ultimate intake upgrade:

• Sealed Housing Design: The enclosed intake box ensures the air filter only draws cold air from outside the engine bay, preventing heat soak and maintaining consistent performance.

• Premium Intake Tube: The lightweight, CAD-designed intake tube is engineered for maximum airflow velocity, eliminating turbulence and providing a stunning look under the hood.

• Pro DRY S Oil-Free Filter: Features a high-flow, oil-free synthetic air filter element (white) that provides maximum filtration efficiency without the risk of damaging your MAF sensor with filter oil.

• Direct Bolt-On Fitment: Designed to fit perfectly onto the factory mounting points. No cutting, drilling, or custom fabrication required. Ideal for DIYers.

• Improved Efficiency: Cooler air equals better combustion, which can lead to improved fuel mileage during daily driving.
