BMW F3X B48 2.0L Engine Cold Air Intake System w/ Heat Shield & Ducting | Fits 2, 3, 4 Series (2016–2019) - 230i 320i 330i 420i 430i

Invigorate your BMW B48’s performance with our upgraded Cold Air Intake System.

The B48 engine is part of BMW’s modular B-Series lineup, succeeding the well-regarded N-Series. Known for its efficiency and strong power-per-cylinder design, the B48 responds extremely well to breathing upgrades. One of the simplest yet most effective ways to unlock additional horsepower and torque is by replacing the restrictive factory airbox with an open-element cold air intake paired with a precision-fit heat shield.

This upgraded intake allows the filter to pull air from a full 360° angle, drastically improving throttle response and enhancing overall drivability—especially when paired with a tune. Beyond performance gains, it also delivers a more aggressive intake note, giving your BMW a sportier, race-inspired sound.

For enthusiasts chasing higher horsepower numbers, this is an essential upgrade to maximize the full potential of your B48 engine.

Key Features:

• Increases horsepower and torque (further gains with tuning)
• Heat shield included to protect against hot engine bay air
• Enhanced engine sound with a sporty induction “whoosh” under throttle
