Why this performance filter works

The triple-density foam construction delivers outstanding filtration without choking the intake. A coarse outer layer captures the big particles, a mid layer stops the bulk of the debris, and a fine inner layer takes care of the rest. The result is high flow that stays high, maintaining performance where thin paper or cotton elements start to clog and restrict.

Real-world confidence

We use these on customer cars and our own builds. Feedback is consistently positive: crisper throttle response, a more engaging intake note and a fit-and-forget solution that outlasts disposable paper filters. It is the ideal supporting modification for a stock or tuned turbo six-cylinder 540i.

Fitment and installation

Designed for BMW 540i G30 models, this reusable intake filter drops straight into the OEM airbox with no cutting or mapping required. Installation typically takes just a few minutes with basic tools.
