What is a BMW M135i GPF / PPF / OPF Delete?

The factory Gasoline Particulate Filter (GPF), also known as a Petrol Particulate Filter (PPF) or Otto Particulate Filter (OPF), is fitted to reduce un burnt fuel particles on modern petrol vehicles. It is also the most restrictive parts of the factory exhaust system.

Our BMW M135i F40 GPF Delete replaces the restrictive filter with a free flowing stainless steel section, allowing exhaust gases to exit more efficiently. This improves exhaust flow, reduces back pressure and unlocks a much more exciting exhaust note.
