Why does the factory BMW N55 charge pipe fail?

The OE intake-side pipe on the N55 is plastic and weakens progressively through heat cycles. Under elevated boost — particularly on tuned cars — it is prone to splitting or cracking, causing a boost leak that results in significant power loss or full limp mode. The BMW N55 charge pipe kit replaces it with aluminum, permanently eliminating that failure mode.

Will this BMW N55 charge pipe kit fit my M2 Competition?

No. The M2 Competition uses the S55 engine rather than the N55 and requires the S55-specific charge pipe kit. This kit is for N55-powered F87 M2 models only (2016-2018).

Do I need a tune to install the BMW N55 charge pipe kit?

No. The kit works on stock and tuned cars alike. If a tune is planned, fitting the aluminum charge pipe beforehand is one of the most important reliability upgrades to complete first, since the plastic OE pipe becomes increasingly vulnerable as boost increases.

What is the injection bung on the BMW N55 charge pipe for?

The 1/8 inch bung accepts a methanol or water injection nozzle. If injection is not being run, the bung ships sealed and can be left plugged permanently without affecting the kit's function.

Is this the complete BMW N55 charge pipe upgrade, or do I need additional parts?

This kit covers the intake-side charge pipe. For a complete upgrade, MMX recommends pairing it with the N55 turbo-side charge pipe kit, which addresses the other half of the charge pipe circuit. Both sides together eliminate every plastic failure point in the N55 charge pipe run.

MMX N55 Charge Pipe Kit (Intake Side) for F20, F22, F30, F32, and F87 BMW

BMW N55 charge pipe kit from MMX Performance permanently fixes one of the most well-known failure points on N55-powered F-chassis BMWs, covering the F20/F21 1 Series, F22/F23 2 Series, F30/F31 3 Series, F32/F33 4 Series, and F87 M2. The factory intake-side charge pipe is plastic, and under elevated boost, particularly on tuned cars, it is prone to splitting and cracking, causing boost leaks that range from a significant power loss to a full limp-mode event. The BMW N55 charge pipe kit replaces it with an aluminum pipe that eliminates that failure mode: smooth-bore internals flow better than the factory setup, resist deformation under boost and vacuum, and CNC-machined hose ends with a supplied silicone coupler deliver a leak-free installation. A 1/8 inch methanol and water injection bung is built in and ships sealed; leave it plugged if injection is not in use. Finished in a durable crinkle black powder coat with laser-etched MMX logo detailing; OE-spec hardware included for direct fitment. This is the intake-side pipe; MMX recommends pairing with the N55 turbo-side charge pipe kit for a complete upgrade.

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.
