Is this suitable for a tuned N55 or stock only?

Both. The MMX BMW N55 charge pipe is a worthwhile reliability upgrade even on a stock car — the OEM plastic unit is marginal even at factory boost levels. For any N55 running a tune with elevated boost, replacing the plastic charge pipe before adding power is a prerequisite, not an option.

Does it use a clamp or the factory c-clip system?

The MMX N55 charge pipe uses the factory c-clip retention system at the throttle body connection, which provides a more secure and OEM-style seal than a conventional clamp-and-coupler design. A new c-clip is included in the kit.

Will this fit the F87 M2 as well as the 335i and M135i?

Yes. The MMX BMW N55 charge pipe kit fits the F87 M2 (2016-2018), F30/F31/F34 335i (2011-2016), F20/F21 M135i (2012-2016), and F30 ActiveHybrid 3 (2012-2015) — all N55-equipped F-series models.

How difficult is installation?

Level-2 install difficulty. The charge pipe is a direct replacement using the factory mounting points and the included c-clip. Access to the turbo-side charge pipe requires removing some engine bay components but no cutting, drilling, or permanent modification is needed.

MMX Turbo-Side Charge Pipe Kit for Fxx BMW M135i, M2, 335i, and ActiveHybrid 3 (N55 Engine)

BMW N55 charge pipe kit from MMX Performance is a high-flow aluminum replacement for the factory plastic turbo-side charge pipe on F-series N55-powered M135i, M235i, M2, 335i, and ActiveHybrid 3 models. The OEM plastic charge pipe is a documented weak point at stock boost levels it is marginal, and under increased boost from a tune, it is a known failure point, prone to cracking, splitting, or blowing off at the throttle body connection and causing boost leaks, limp mode, and potential engine protection events. The MMX aluminum charge pipe eliminates that failure risk with a lightweight, high-flow unit that maintains its shape under elevated boost pressure and vacuum cycling. The smooth internal bore reduces turbulence, sharpens throttle response, and delivers consistent airflow to the throttle body. CNC-machined connections ensure a precise, leak-free fit using the factory c-clip retention system; a new c-clip is included. Finished in a durable crinkle black coating with laser-etched MMX branding.

Frequently Asked Questions

Why does the BMW N55 charge pipe need replacing? The factory BMW N55 charge pipe is made from plastic and is a known failure point under stock and elevated boost levels. It is prone to cracking or splitting at the throttle body connection, causing boost leaks, limp mode, and potential engine protection events. The MMX aluminum N55 charge pipe eliminates that failure risk with a rigid, high-flow unit that maintains its shape under sustained boost pressure and vacuum cycling.

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.
