High‑flow panel filter for BMW 545i and 550i V8 E60 E61

Give your V8 the breath it deserves. This reusable cotton panel drops straight into the original airbox, improving engine response and induction tone while retaining everyday drivability. It is a simple, proven upgrade for anyone who wants stronger mid‑range pull and a smoother throttle without converting to a full intake system.

Real‑world results

We have installed this panel on multiple BMW V8 5 Series models and customer feedback has been excellent. Owners report a more eager rev‑up, a subtly richer induction note and a cleaner pull through the rev range. It is a great pairing for a stock car or one with a cat‑back exhaust.

Maintenance

When the element becomes dirty, use a suitable cleaning and re‑oil kit, allow it to dry, then refit. Properly serviced, this is designed to be the last filter your car will need.
