Dinan Closed Cold Air Intake for 2016-2021 BMW 230i/330i/430i | D760-0048

The Dinan Closed Cold Air Intake (D760-0048) is an engineered performance solution for the 2016-2021 BMW 230i/330i/430i (B46/B48 engine), following a thorough methodology designed to maximize engine efficiency and sound. This intake improves upon the factory design by utilizing a larger airbox (30% larger than stock) and filter element, which improves throttle response and lessens the strain on the turbocharger. The key is the fully carbon construction, which includes an optimized carbon fiber intake tube that eliminates the flow-disrupting baffling and Helmholtz chamber found in the stock configuration. This thorough design methodology elicits verified gains of $+6HP and +6lb-ft of torque at 5000 RPM on a completely stock vehicle. The system is completely sealed to ensure only cold, outside air is employed, maximizing efficiency.

Features:

• Verifiable Power Gains: Delivers an impressive gain of +6HP and +6lb-ft of torque at 5000 RPM without additional modifications.

• Flow Optimization: Features a 30% larger volume air box and a 34% increase in filter area ($102.1 in² vs stock 76.3 in²) for optimum flow.

• Optimized Design: Incorporates an optimized carbon fiber intake tube and a free-flowing injection molded Air Mass Meter housing (over 20 larger than stock) to eliminate flow disruptions.

• Thermal Integrity: The air box is a completely sealed system for maximum insulation from power-robbing engine bay heat.

• Compliance: 50 State Emissions Legal for certain applications: CARB EO D-176-56 (2019-21 F2x/F3x 230i/330i/430i only).
