BMW 6 E64 Parts

The E64 convertible is one of those Bimmers that gets overlooked in the enthusiast conversation, and honestly, that's a mistake. Built from 2004 to 2010, the E64 is the drop-top sibling to the E63 coupe - sharing the same platform, the same brilliant chassis, and the same engine lineup that made the 6er one of BMW's most capable grand tourers of the era. It's long, it's low, it's confident on the highway, and with the right work underneath it, it's a genuinely exciting driver's car. The soft top is power-operated, the cabin is premium without being precious, and the whole package has aged incredibly well. If you can find a clean one at today's used prices, you're getting a lot of BMW for the money.

The E64 came stateside in two main flavors: the 645Ci (2004–2005) running the naturally aspirated 4.4L V8 (N62), and the 650i (2006–2010) with the refined 4.8L N62B48 making 360 horsepower. Both are smooth, characterful engines with a distinctive V8 note that opens up beautifully with the right exhaust work. The M6 convertible also falls under the E64 umbrella with its legendary S85 V10 - a whole different animal and a whole different maintenance budget. For most enthusiasts working with the 645Ci or 650i, the N62 is where your focus will be. It's not a turbo motor, so don't expect N54-crowd power-per-dollar ratios, but there's real performance locked inside these engines with the right supporting mods. Bolt-ons, tune, and a proper suspension setup will transform how this car drives.

Let's be straight with you - the N62 has its quirks, and knowing them upfront saves you serious money and headaches. The valley pan gasket is the N62's most notorious weakness. Oil seeps from the intake valley area and it's a labor-intensive fix, but it's not a reason to walk away from the platform - it's just something to budget for and address proactively. The Valvetronic motor and eccentric shaft sensors are also known to cause issues as mileage climbs; keep an eye on rough idle and inconsistent throttle response as early warning signs. Cooling system maintenance is non-negotiable on these cars - water pump, thermostat, and expansion tank should be treated as wear items, not lifetime components. The SMG-equipped cars are smooth when they're healthy, but SMG pump failure is a real concern, and many owners have moved toward ZF 6-speed automatic swaps or simply prefer the cars spec'd with the traditional auto from the factory.

On the suspension side, the E64 uses a sophisticated setup that handles road miles well but needs attention around the 80–100k mark. Control arm bushings, thrust arm bushings, and front strut mounts are your priority refresh items. A worn front end will kill your steering feel and make even a well-powered car feel vague and disconnected. Don't skip this - a fresh suspension makes a night-and-day difference on these chassis. Check out our full catalog under Suspension for E64-specific fitment including Bilstein, KW, and H&R options that work well with this platform.

The brakes on the stock 650i are adequate but not inspiring for spirited driving. If you're pushing this car on back roads or occasional track days, upgrading to slotted rotors and quality pads is a smart early investment. For any serious brake or Engine work, having a solid ISTA diagnostic setup or a trusted indy shop that knows BMWs is essential - these aren't cars you want to wrench on blind.

The E64 rewards a specific kind of build philosophy. This is a grand touring convertible at its core, and the best builds respect that DNA while sharpening what's already there. For a refined daily driver, the priorities are clear: start with a quality stainless exhaust to wake up the N62's V8 character - check the options in our Exhaust section including Supersprint and Eisenmann, both of which have strong fitment for the 645Ci and 650i. Follow that with a suspension refresh and a mild drop using H&R sport springs for improved stance and sharper response without destroying ride quality. A good set of 19-inch forged wheels on quality summer tires transforms both the visual presence and the dynamic feel - browse our Wheels & Tires section for staggered fitments that work perfectly with E64 offsets.

For those wanting to push a little harder, a proper ECU tune from a reputable shop unlocks more from the N62 than most people expect. Pair that with cold air intake, upgraded exhaust, and a limited-slip differential if you can source one, and you've got a 6er that moves with real authority. On the exterior, the E64 responds well to subtle aero upgrades - a factory M Sport front lip, side skirts, and trunk spoiler tighten up the look without going boy-racer. See what's available under Body & Aero for OEM-style upgrades that fit the character of the car.

Trusted brands for this platform include Bilstein for dampers, Meyle HD and Lemforder for suspension components, Genuine BMW or Mahle for cooling system parts, and Turner Motorsport for a solid range of E6x-compatible upgrades. The E64 community is smaller than the E9x crowd but passionate - and parts availability is still strong. This is a Bimmer worth investing in.
