Ramair Pleated Intake Kit for BMW GXX M240i/340i/440i
Unlock smoother airflow and a crisper throttle with this Ramair pleated intake kit for BMW G-series six-cylinder models. It replaces the restrictive factory airbox with a free-flow design, a sealed heatshield, and a smart two-piece carbon fibre cover to help keep intake temperatures in check. You will hear a deeper induction tone and more turbo sound under load.
Why choose this intake
- Improved airflow for better response and power potential
- Sharper throttle feel, especially in the mid-range
- Richer turbo induction sound without drone
- CNC-cut heatshield and carbon fibre cover help reduce heat soak
- Rotomoulded intake pipe for smooth, consistent flow
- High-flow pleated filter with large surface area, washable and reusable
- Direct fit using factory mounting points, with fittings and instructions included
What it does: the stock airbox can cause pressure drop, which makes the turbo work harder. This kit reduces restriction and smooths the airflow path to the turbo. On a standard car, expect a small but noticeable improvement in response and intake sound. With a performance remap and supporting mods, the higher flow capacity can help the engine make and hold more power.
