What does the BMW S55 panel air filter improve over the factory paper element?

The MMX BMW S55 panel air filter uses tri-foam motorsport-derived construction to flow significantly more air to the S55 turbos than the restrictive factory paper element, improving throttle response, induction character, and overall engine performance. Unlike the paper element, the tri-foam filter is designed for long-term reuse rather than periodic replacement.

Does this filter also fit the S63-powered M5 and M6?

Yes. In addition to S55-powered models, the BMW S55 panel air filter set fits the F10 M5 and F12/F13 M6 equipped with the S63 4.4L V8 twin-turbo. Fitment on the F06 Gran Coupe M6 is not confirmed — contact us before ordering for that specific chassis.

Does the BMW S55 panel air filter require any modifications to fit?

No. The BMW S55 panel air filter is a direct OEM replacement that fits precisely within the factory airbox with no modifications, no additional hardware, and no cutting required. Installation takes approximately 10 minutes and is fully reversible.

Why is this sold as a pair?

The S55 and S63 engines each use two panel filter positions in the OEM airbox. Replacing both simultaneously ensures matched airflow and filtration performance across both positions rather than running one new and one old element.

Is this a panel filter or a cone filter?

The BMW S55 panel air filter is a panel-style drop-in replacement for the OEM airbox, retaining the cold-air and sealed-box benefits of the factory setup. It is not a cone filter or an intake kit, so there is no compromise on cold-air intake temperature management.

Description

MMX Elite Series Panel Air Filters for F8x/F1x BMW M2 Competition, M3, M4, M5, and M6 (S55 and S63)

BMW S55 panel air filter from MMX Performance is the Elite Series replacement for the restrictive factory paper elements in S55 and S63-powered F-chassis BMW M cars, covering the F87 M2 Competition and M2 CS, F80 M3 and M3 CS, F82/F83 M4, M4 CS, M4 GTS, F10 M5, and F12/F13 M6. The factory paper filter elements on S55 and S63 engines restrict airflow to the turbos and represent one of the simplest, most cost-effective first upgrades available on the platform. The MMX BMW S55 panel air filter uses tri-foam construction and motorsport-derived materials developed from technology used in Formula 1, World Rally, and Touring Car applications to eliminate those restrictions, delivering significantly improved airflow to the turbos, enhanced throttle response, improved induction sound, and measurable performance gains on both road and track. Designed to integrate precisely with the factory airbox as a direct OEM replacement, each filter is manufactured to OEM standards for fit, durability, and filtration efficiency with none of the cold-air box compromise that open cone filter setups introduce. Installation takes approximately 10 minutes with no modifications; sold as a pair covering both filter positions.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
