MMX Elite Series Panel Air Filter for N55-Powered BMW F-Chassis Models
BMW N55 panel air filter from MMX Performance is the Elite Series replacement for the restrictive factory paper element in N55-powered F-chassis BMWs covering the F30/F31 335i, F32/F33 435i, F07/F10/F11 535i, F06/F12/F13 640i, F01/F02/F03 740i and 740Li, F20/F21 M135i, F87 M2, F22/F23 M235i, and N55-equipped X3, X4, X5, and X6 xDrive35i models. The factory paper filter element limits airflow to the N55 turbo and represents one of the lowest-cost, highest-impact first upgrades available on the platform. The MMX BMW N55 panel air filter uses tri-foam construction and motorsport-derived materials developed from technology used in Formula 1, World Rally, and Touring Car applications, eliminating those airflow restrictions and delivering improved turbo efficiency, enhanced throttle response, and better induction character on both road and track. Precision-molded to fit directly into the factory N55 airbox as a direct OEM replacement no modifications, no additional hardware, installs in approximately 10 minutes. Manufactured to OEM standards for fit, durability, and filtration efficiency; suitable for stock and tuned N55 cars.

Frequently Asked Questions
- What does the BMW N55 panel air filter improve over the factory paper element? The MMX BMW N55 panel air filter uses tri-foam motorsport-derived construction to flow significantly more air to the N55 turbo than the restrictive factory paper element, improving throttle response, induction character, and engine performance. The tri-foam construction is designed for long-term reuse rather than periodic replacement like a paper filter.
- Does this BMW N55 panel air filter fit the F87 M2 as well as the 335i and 435i? Yes. The BMW N55 panel air filter fits every N55-powered F-chassis model in the Applications list, including the F87 M2 (2016-2018 N55 base model), F20/F21 M135i, F22/F23 M235i, and N55 xDrive35i X-series models, as well as the 335i, 435i, 535i, 640i, and 740i.
- Does the BMW N55 panel air filter require any modifications to fit? No. The BMW N55 panel air filter is precision-moulded to fit directly into the factory N55 airbox as a direct OEM replacement with no modifications, no additional hardware, and no cutting required. Installation takes approximately 10 minutes and is fully reversible.
- Is this filter suitable for a tuned N55? Yes. The BMW N55 panel air filter is suitable for stock and tuned N55 engines, and is a sensible first upgrade to fit before or alongside a tune since improved airflow allows the engine management to take fuller advantage of increased boost.
- Is this a panel filter or a cone filter? The BMW N55 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.

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.
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.

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
