BMW 645Ci Parts & Accessories

Shop BMW 645Ci intake, brake and suspension parts at Black Ops Auto Works. Explore an aFe N62 Pro 5R intake, EBC brake packages and separate H&R spring options for the E63 coupe and E64 convertible. Plan the V8 service and chassis changes together, whether you are maintaining a road car or developing a more involved 6 Series project.

aFe N62 Induction and Dinan Ignition

The aFe 54-11081 Stage-1 Pro 5R intake names 2004–2005 645Ci 4.4L V8 applications. Its reusable oiled-cotton filtration provides an induction project with a defined care routine. Compare the supplied components with the existing intake, then match the actual engine and connections before ordering.

Dinan N-Series ignition coils offer blue, red and black housings for supported engines. Choose the exact coil reference and service quantity first, then select the engine-bay finish. Match plugs from the prescribed engine specification or approved tune, separately from the intake choice.

EBC Brake Packages by Compound and Disc Design

The selection includes EBC S9 front-kit references naming the 645Ci and an S4 package pairing Redstuff pads with USR rotors. Redstuff is a low-dust fast-road option where its complete brake application supports the car. Compare the actual compound and disc design inside each kit rather than choosing from the stage number alone.

Use measured rotor condition to decide between pads alone and a wider axle refresh. Match the installed caliper, axle and disc dimensions, then compare the required sensors and hardware with the supplied kit contents. Front and rear service need their own component plan.

H&R Springs for Coupe or Convertible

The listed H&R E63 coupe spring option carries Dynamic Drive and non-convertible application notes. The E64 convertible package has separate body coverage. Choose the exact spring reference around the actual suspension equipment, desired stance and retained dampers.

Plan mount condition, suspension travel, wheel clearance and alignment with the installer. Dinan’s front carbon-fiber strut-tower brace offers another chassis detail for its supported installation, with its own mounting requirements.

Wheel Spacers and Matching Bolts

Dinan spacer pairs include stated 5×120 and 72.6 mm center-bore choices in several thicknesses, alongside aFe CONTROL options. Measure the wheel position you want and the available clearance, then select thickness and matching fasteners together. Confirm bolt thread, seat and usable engagement for the complete wheel-and-hub arrangement.
