To propel these hefty, yet capable, luxury vehicles, a large volume of air is required to be fed into two powerful turbochargers. The stock airboxes that provide this air utilize restrictive panel filters and artificially limit air volume. With a few small tweaks, however, a more efficient system with increased flow capacity that yields more power can be achieved. That is exactly what Dinan has done with the revised and improved carbon fiber cold air intake system for the M550i and M850i. Retaining the factory lower boxes for simplicity but enlarging the air box lids via the removal of the unused "U" channels afforded the opportunity to be able to not only increase volume by 54%, but also allowed the use of bespoke high-flow cone filters with 22% more surface area than the factory panel filters. The improvements continue down the intake tract with the enlarged volume of air transitioning into an organically shaped intake pipe that grants a more natural and unhindered flow path into the turbo. The combination of these improved features means the engine is allowed to ingest more cold air with less restriction resulting in top end gains of +17 WHP / +18 ft-lbs of torque.

Installation Instructions
  • More Power: Max gains of 17 WHP and 18 lb-ft of torque @ 5500 RPM without additional modifications
  • 34% increase in filter area (stock: 76.3in², Dinan: 102.1in²) for optimum flow
  • Larger volume air box (54% larger than stock) for increased breathability
  • Sealed system ensuring only colder outside air is utilized
  • Quick and easy installation
  • Improved throttle response
  • Outflows factory intake

DINAN FREQUENTLY ASKED QUESTIONS

HOW DO I CONFIRM A DINAN PART FITS MY VEHICLE?

Start with the year, make and model selector, then confirm the chassis code, engine, drivetrain and any application notes on the product page. BMW and MINI models from the same year can use different engines or hardware. If anything is unclear, contact FI Performance with your VIN and the Dinan part number before ordering.

DO CHASSIS CODE, ENGINE AND FACTORY OPTIONS MATTER?

Yes. Dinan fitment can depend on chassis generation, engine code, production date, transmission, rear- or all-wheel drive, factory suspension, brake package and other equipment. A model name alone is not always enough to establish fitment.

DO DINAN INTAKES AND AIRFLOW PARTS REQUIRE TUNING?

Many Dinan intake and airflow upgrades operate safely without additional software, while some applications achieve their advertised results only when paired with compatible tuning or supporting hardware. Follow the requirements listed for the exact part number and vehicle application.

WHAT SHOULD I EXPECT FROM A DINAN EXHAUST?

Dinan exhaust systems are designed to add a deeper, more purposeful tone while maintaining refined street manners. Sound level, cold-start volume and cabin presence vary by vehicle, exhaust section, drive mode and other installed components. Review the exact product description before ordering if sound level is a primary concern.

WILL DINAN SUSPENSION OR CHASSIS PARTS CHANGE RIDE QUALITY?

They can. Springs, dampers, sway bars, braces and related chassis parts may produce a firmer or more controlled ride depending on the combination and settings used. A professional alignment is recommended after installing components that alter ride height or suspension geometry.

WHAT IS REQUIRED AFTER INSTALLING DINAN BRAKE PARTS?

Brake components must be installed to the vehicle and product specifications. New pads and rotors should receive the correct bedding procedure, and the system should be inspected for proper operation before normal driving. Brake work should be completed by a qualified technician if you do not have the required tools and experience.

DO DINAN ENGINE AND TUNING PRODUCTS REQUIRE SPECIAL INSTALLATION?

Requirements vary. Some inline modules are designed for straightforward sensor connections, while software, turbochargers and other advanced engine upgrades may require special tools, programming, supporting modifications or professional installation. Use Dinan's instructions for the exact part number and do not substitute instructions from another application.

HOW DO I CHOOSE THE CORRECT WHEELS, SPACERS AND HARDWARE?

Confirm wheel diameter, width, offset, center bore, brake clearance and tire fitment for the vehicle. Spacers must use the correct bolt pattern, hub fitment and matching extended hardware where required. Never stack wheel spacers, and always follow the specified torque procedure and recheck schedule.

HOW ARE DINAN EXTERIOR AND INTERIOR PARTS INSTALLED?

Installation ranges from direct replacement to adhesive bonding, trimming or removal of factory panels. Dry-fit cosmetic parts before final installation and follow the supplied surface-preparation and curing instructions. Professional installation is recommended for carbon-fiber pieces or any part requiring permanent modification.

ARE DINAN DRIVETRAIN AND SHIFTING UPGRADES STREET FRIENDLY?

Dinan designs many drivetrain and shifting upgrades to improve response and driver engagement without sacrificing everyday usability. Increased shift effort, vibration or mechanical feedback can still occur depending on the part and vehicle. Check the product notes for the expected change before purchase.

ARE ALL DINAN PERFORMANCE PARTS EMISSIONS LEGAL?

No. Emissions status is part- and application-specific. Some products are 50-state legal, some are not legal for sale or use in California, and others may be intended only for competition vehicles. Review the emissions statement and any CARB Executive Order listed for the exact part and vehicle before ordering or installing it.

WHO SHOULD INSTALL DINAN PERFORMANCE PARTS?

Installation difficulty varies by category and application. Always review Dinan's part-number-specific instructions first. Safety-critical, software, engine, suspension, brake and permanently bonded components should be handled by a qualified performance shop when the procedure exceeds your tools or experience.

WHAT WARRANTY APPLIES TO DINAN PRODUCTS?

Warranty coverage varies by product, vehicle and installation. Dinan states that its performance products generally carry a two-year, unlimited-mileage warranty, while certain qualifying products or applications may have different or factory-matching coverage. Warranty does not cover problems caused by improper installation, misuse, misapplication, modification or neglect. Review the current Dinan warranty terms for the exact product before purchase.
