Does the Dinan M5 cold air intake fit the M5 Competition?

Yes. The Dinan M5 cold air intake fits the F90 BMW M5 (2018-2023), including the M5 Competition, since both use the same S63 4.4L twin-turbo V8 and intake architecture. It bolts to the factory mounting points for a direct fit.

Is it a sealed intake?

Yes. The Dinan M5 cold air intake uses sealed airboxes that isolate the high-flow filters from hot underhood air, keeping intake temperatures down. Cooler, denser air helps both turbochargers respond more consistently under load.

The intake tubes are carbon fiber for a smooth, low-restriction path and a clean underhood look. The filters are high-flow, washable, and reusable, so they can be cleaned rather than replaced over the life of the car.

No tune is required to run the Dinan M5 cold air intake, and it improves airflow on its own. The intake pairs well with engine tuning, which lets the S63 take fuller advantage of the cooler, freer-flowing air for stronger, more repeatable gains.

Is installation difficult?

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 F90 M5.

Description

Dinan Carbon Fiber Cold Air Intake for F90 BMW M5

The Dinan M5 Cold Air Intake is a carbon fiber induction system for the F90 BMW M5 and its S63 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 result is sharper throttle and turbo response and a more purposeful intake note, with a clean carbon look under the hood. Finished in exposed carbon fiber.

Features

Larger volume air boxes (31% larger than stock) that completely seals allowing an increased volume of air to be utilized
Center wishbone inlet/scoop incorporated as an additional secondary air source for maximum airflow
35% increase in filter area (stock: 56.5in², Dinan: 80in² per side) for optimum flow
More Flow: 11% greater than stock (Stock: 575 CFM, Dinan: 637 CFM @ 28″ H2O per bank)
Increased turbo efficiency, reliability, and head room

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.
