Description

Dinan Carbon Fiber Cold Air Intake for G30 BMW M550i and G14 / G15 / G16 M850i

Dinan M550i intake is a sealed, dual-airbox carbon fiber induction system for the G30 BMW M550i and the G14, G15, and G16 M850i, both powered by the N63 4.4L twin-turbo V8. Dinan swaps the restrictive factory setup for larger sealed airboxes, larger high-flow filters, and optimized carbon fiber tubes that cut restriction and shield the filters from underhood heat, feeding cooler, denser air to both turbochargers. The sealed boxes are 54% larger than stock, for sharper throttle and turbo response and up to 17whp and 18ft-lb at 5,500rpm without additional modifications, with a clean carbon look under the hood.

Frequently Asked Questions

Does the Dinan M550i intake fit the M850i? Yes. The Dinan M550i intake fits the G30 BMW M550i from 2020 through 2023 and the G14 convertible, G15 coupe, and G16 Gran Coupe M850i from 2019 through 2026, both running the N63 4.4L twin-turbo V8. It bolts to the factory mounting points for a direct fit.
How much power does the Dinan M550i intake add? The Dinan M550i intake makes max gains of 17 whp and 18 ft-lb at 5,500 rpm without additional modifications, with dual sealed airboxes 54% larger than stock and 34% more filter area. Feeding cooler, denser air to both turbochargers sharpens throttle and turbo response, with the gains growing further on a tuned car.
Is the Dinan M550i intake a sealed intake? Yes. The system uses dual sealed airboxes that isolate the high-flow filters from hot underhood air, ensuring only colder outside air is drawn in. Cooler, denser air keeps the N63’s twin turbos responding more consistently under load.
Are the filters on the Dinan M550i intake reusable? Yes. The intake uses high-flow filters that are washable and reusable, so they can be cleaned and re-oiled rather than replaced. The larger filter area supports the intake’s higher airflow while protecting the N63 V8.
Is the Dinan M550i intake difficult to install? No. The intake is a bolt-on installation using the factory mounting points with no cutting required. The kit includes the carbon fiber tubes, sealed airboxes, and high-flow filters needed to complete the swap on the M550i or M850i.

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.
