BMW M440i Parts & Accessories

Choose BMW M440i upgrades around your preferred sound, stance and everyday use. Black Ops Auto Works offers AWE, Dinan and MagnaFlow exhaust packages, B58 intake and cooling components, suspension options and brake-service parts. Compare the exact coupe, convertible or Gran Coupe application before combining the project.

Exhaust and Intake Options

The listed AWE non-resonated Touring system includes quad Diamond Black tips; its application excludes the G2X Gran Coupe. Dinan axle-back and MagnaFlow SPEQ cat-back packages have their own body coverage and installation scope. Compare resonance control, valves, finishing pieces and the current downpipe to choose the sound and total package. For induction, distinguish a full Dinan intake from an inlet pipe, including earlier versus Gen 3 B58 inlet coverage.

Cooling and Suspension Projects

do88 separates B58 charge-cooler manifolds, auxiliary radiators and transmission coolers for their specified circuits. CSF adds oil-cooler and manifold options, with the No Limit competition manifold requiring a much broader external-intercooler build. Identify the system being changed before comparing parts or labor. For suspension, choose the actual body and drivetrain first: the listed AST spring ranges and lowering figures are separate applications, not interchangeable height options for every M440i.

A Simple Parked-Cabin Protection Project

The listed blue Covercraft UVS100 UV11773BL shade names 2021–2023 4 Series coupe windshield coverage. Its reflective face, insulating core and folding format serve parked-cabin protection. Review the exact windshield pattern before selecting it; that coupe application does not establish Gran Coupe coverage.

Brake Service and Wheel Details

For a brake refresh, compare pads, rotors and sensors against the installed package, axle and disc material, then choose the compound for how the car is used. Dinan spacers and wheel bolts address a separate mounting project. Measure clearance and confirm hub dimensions, wheel seat and fastener engagement before choosing thickness and bolt length.

Frequently Asked Questions

Does the AWE Touring package cover the Gran Coupe?

The listed non-resonated Touring application excludes the G2X Gran Coupe. Choose an exact package with explicit coverage for your body, then compare the supplied tips and system sections.

How do I choose between an intake and an inlet pipe?

Compare the section each component replaces and its supplied parts. Match the actual B58 generation and current air-path connections, then review required companion components for the combination.

Can I choose AST springs just by the stated lowering amount?

Choose the supported body, drivetrain, production range and factory suspension first. Compare the stated drop only within the correct application, with damper condition, travel, clearance and alignment planned together.

Should I buy replacement rotors or a full brake package?

Inspect the actual discs, pads, sensors and hardware for the axle being serviced. Match the installed caliper and disc specification, then choose the parts needed for the repair and intended use.

Is a CSF oil cooler the same project as its No Limit manifold?

No. An oil cooler serves the specified engine-oil circuit. The No Limit manifold belongs to a competition build with an external intercooler and extensive supporting work. Compare the complete system plan rather than just the two component prices.
