Cold Air Intake for BMW 2 Series 4 Series (2022-2025) 2.0L

High-Flow Cold Air Intake for 2022-2025 BMW 2 Series,4 Series (G42, G22, G23, G26)

What it Does: The Cold Air Intake replaces the restrictive factory airbox and corrugated ducting on the 2022-2025 2 Series,4 Series to lower intake air temperatures and accelerate turbocharger spool.

The Stock BMW 2 Series,4 Series Intake Restriction and Thermal Soak

The factory intake tract on B48-equipped vehicles relies on a baffled, tortuous airbox tuned strictly for sound attenuation over volumetric efficiency. Corrugated plastic piping introduces boundary-layer turbulence right before the turbo inlet, while the unshielded OEM layout sits exposed to radiant engine bay heat. This design invites thermal saturation under sustained boost, causing elevated intake air temperatures (IATs) and triggering the factory ECU to retard ignition timing.

The Engineering Solution

This intake upgrades the induction path with a smooth-bore, black powder-coated turbo inlet pipe paired to a massive 3.5-inch conical air filter. A dedicated black powder-coated heat shield forms a barrier against exhaust manifold heat wash, channeling dense, ambient air directly to the compressor inlet. By smoothing airflow and reducing pre-turbo pressure drop, the kit yields verified gains of 8 to 12 horsepower at 4,000 RPM, sharpens throttle response, and enhances turbo spool acoustics without setting off lean fault codes.

Frequently Asked Questions & Fitment Warnings

Does this fit the G42 and G22 2 Series,4 Series?

Yes, this is a direct fit for the 2022-2025 BMW 2 Series,4 Series equipped with the B48 / B46 2.0L turbo engine. Does not fit 3.0L 6-cylinder B58 models such as the M240i or M440i.

What is the recommended filter maintenance schedule?

Clean the 3.5-inch filter element every 20,000 km (12,000 miles) and replace it completely every 60,000 km (36,000 miles) for optimal airflow.

The BMW Precision Standard

Designed to maintain OEM mass airflow meter scaling, this intake allows European performance enthusiasts to upgrade airflow velocity without triggering check engine lights or disrupting factory closed-loop fuel trims.
