Which models does the Dinan M440i cold air intake fit?

The Dinan M440i cold air intake fits the G20 BMW M340i, G22, G23, and G26 M440i, and G42 M240i (2020-2026), all with the B58 turbocharged inline-six. It is compatible with cars with and without factory bracing.

How much power does it add?

The Dinan M440i cold air intake is good for max gains of 9 wheel horsepower and 8 lb-ft of torque at 6500 RPM on a completely stock vehicle, from a 60 percent larger air box and 58 percent more airflow than stock.

Is it compatible with a strut brace?

Yes. Unlike some intakes, the Dinan M440i cold air intake is compatible with G2x M-x40i models both with and without factory bracing, so no separate brace-specific version is required.

Is the filter reusable?

Yes. The intake uses a washable, reusable high-flow filter with 40 percent more area than stock, so it can be cleaned and re-oiled rather than replaced while supporting the higher airflow.

Is installation difficult?

No. The Dinan M440i cold air intake is a quick, bolt-on installation using factory mounting points, with no cutting required. The kit includes the carbon fiber tube, sealed air box, and filter needed to complete the swap.

About Dinan

Founded in 1979, Dinan is North America’s leading BMW tuner, developing, manufacturing, and marketing a full line of high-performance products for BMW, MINI, and Mercedes-Benz. Dinan works through a nationwide network of Authorized Dinan Performance Centers, including select BMW dealerships and independent BMW service and performance shops. The company’s warranty program, introduced in 1996 with BMW of North America’s cooperation, matches BMW’s new car warranty and covers Dinan enhancements and the vehicle itself for up to 4 years or 50,000 miles. That coverage lets BMW owners add real performance without risking their factory warranty. Automotive publications have tested Dinan-enhanced BMWs against some of the world’s most exotic sports cars for three decades, and the results consistently hold up. Despite that performance, Dinan BMWs keep the reliability and everyday civility BMW owners expect. The product line spans engine, driveline, and chassis components across the full BMW lineup, covering acceleration, cornering, and stopping power. Every Authorized Dinan Performance Center can help build anything from a single upgrade to a complete Dinan BMW.

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.
