What does the BMW N57 panel air filter improve over the factory paper element?

The MMX BMW N57 panel air filter uses tri-foam motorsport-derived construction to flow significantly more air than the restrictive factory paper element, improving turbo efficiency, sharpening throttle response, and enhancing induction character. The filter is also designed for long-term reuse rather than periodic replacement like a paper element.

Does the BMW N57 panel air filter require any modifications to fit?

No. The BMW N57 panel air filter is a direct OEM replacement that fits precisely within the factory N57 airbox with no modifications, no additional hardware, and no cutting required. Installation takes approximately 10 minutes and is fully reversible.

What is tri-foam construction and why does it matter?

Tri-foam construction uses three layers of foam filtration media with different densities, drawing on technology used in motorsport applications including Formula 1, World Rally, and Touring Cars. This layered approach balances high airflow with effective filtration — more air than a paper element without sacrificing particle capture — making the BMW N57 panel air filter suitable for both road and competition use.

Is this filter suitable for a remapped N57?

Yes. The BMW N57 panel air filter works on stock and remapped N57 engines alike, and is a sound first upgrade to fit before a remap 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 N57 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.

Description

MMX Elite Series Panel Air Filter for F3x BMW 330d, 335d, 430d, and 435d (N57)

BMW N57 panel air filter from MMX Performance is the Elite Series replacement for the restrictive factory paper element in N57-powered F-chassis BMWs covering the F30/F31/F34/F35 330d and 335d and the F32/F33/F36 430d and 435d. Where the standard OEM paper element limits airflow to the N57’s twin-turbo diesel system, the MMX BMW N57 panel air filter uses tri-foam construction and motorsport-derived materials developed from technology used in Formula 1, World Rally, and Touring Cars to eliminate those restrictions and allow the turbo to breathe more freely, improving efficiency, sharpening throttle response, and enhancing induction character. The filter fits precisely within the factory N57 airbox as a direct OEM replacement with no modifications and installs in approximately 10 minutes; it is fully reversible and requires no additional hardware. Built to OEM standards of fit and longevity, the Elite Series is designed for both road and competition use, making it the natural first upgrade for any N57-powered BMW before a remap or further performance work.

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.
