aFe POWER Momentum GT Pro DRY S Cold Air Intake System for Select BMW 2017-2021 (I4-2.0L) 51-76312

Fits select 2017-2021 BMW 230i, 330i, and 430i models (I4-2.0L).

The aFe POWER Momentum GT Pro DRY S intake system is engineered to optimize airflow and thermal management for your turbocharged BMW. This system replaces the restrictive factory airbox with a custom-designed solution that outflows the stock intake by up to 14%. The centerpiece is a one-piece, roto-molded sealed housing featuring an auxiliary air inlet for increased volume and a built-in clear sight window for quick filter inspection without disassembly.

To maintain intake velocity and ensure a precise fit, the system utilizes a CAD-designed, dyno-tuned intake tube. The included Pro DRY S filter uses three layers of progressively finer porosity synthetic media, providing high-efficiency filtration without the need for filter oil. An integrated aluminum heat-shield panel protects the intake housing from turbocharger radiant heat, while premium stainless steel clamps and silicone bellow couplings provide a durable, secure installation that requires no cutting or drilling of factory components.
