BMC F1 Replacement Air Filter

Drop-in replacement air filter for the Porsche 986 Boxster and Boxster S (1997-2004), fitting directly into the factory airbox in place of the paper filter. Made by Italian aftermarket air filter manufacturer that also supplies OEM filters to F1 and factory motorsport teams., the outer frame uses a soft rubber material built with a full-molding process for a tight seal that resists cracking, while the washable cotton filter element sits in an alloy mesh screen that protects against debris and holds its shape. It flows nearly 40% more air than the stock paper filter and uses the same media BMC supplies to the Ferrari Formula 1 and GT race teams, plus Porsche, Mercedes-Benz and Audi motorsport programmes. Fabspeed measured gains of 4 whp and 1 lb-ft of torque on the dyno. Lifetime filter, washable and re-oilable rather than disposable.
Frequently asked
Does the BMC F1 Replacement Air Filter fit my Boxster?
This listing is specific to the Porsche Boxster (986). 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.
Does the filter need oiling?
No, it's a washable cotton filter you clean and reuse, and BMC rates it as a lifetime part rather than a disposable one.
Will it fit my airbox without modification?
Yes, it's a direct drop-in for the stock 986 Boxster airbox, with no cutting or mods needed.
How much power does it add?
Fabspeed's testing showed a gain of 4 whp and 1 lb-ft of torque.
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.
