BMC F1 Replacement Air Filters

A washable pair of BMC F1 replacement filters that drop into the BMW M5 (F90)'s factory airbox in place of the paper originals. The cotton element flows nearly 40 percent more air than paper and sits inside an alloy mesh screen that holds its shape under load. BMC supplies the same filter media to the Ferrari, Porsche, Mercedes-Benz and Audi motorsport programmes, and it's a lifetime part rather than a service item, though Fabspeed recommends servicing it roughly every 15,000 miles with a BMC cleaning kit.
Frequently asked
Does the BMC F1 Replacement Air Filters fit my M5?
This listing is specific to the BMW M5 (F90). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
How often do these need servicing?
Fabspeed recommends cleaning and re-oiling the filter roughly every 15,000 miles (25,000km) using a BMC Air Filter Cleaning Kit.
Is this a reusable filter?
Yes, the cotton element is washable and re-oilable, so it's a lifetime replacement rather than a service part.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
