The centerpiece of this MMX kit is the UK-made CNC-machined one-piece crank hub, created from billet EN36 steel that's heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. Included are four aerospace precision-machined dowels that mechanically lock the hub to the end of the crank itself, plus a brand new OE bolt. Installation of these dowels is certainly not a DIY job. But, to make the job easier for the professionals, ensuring that the required crank modifications are made safely and accurately, the MMX kit also includes a full installation jig that includes a bolt-on drilling guide, a location bolt for this guide, plus an HSS rolled high-speed drill bit. Together, the single-piece design combined with the four-pin location ensures that there is simply no way that the friction plates can ever slip. With the new OE crank bolt tightened appropriately, this delivers a transformational improvement in reliability and peace of mind versus the OE version. Also included is the MMR Crank Bolt Capture Plate. This adds one additional layer of defense, preventing the crank bolt from being able to back out and loosen over time, ensuring everything is tightly held together as intended.

There's no avoiding it, your engine's contact surfaces wear a tiny amount each time it runs. So, it becomes inevitable that tiny ferrous particles become suspended in the oil. They quickly make their way around your engine via the oil system for thousands of miles traveling over sensitive components such as your crankshaft bearings or camshaft caps, slowly contributing to increased engine wear. Our magnetic sump plug has a large surface area magnetic end, which helps to catch metal particles. And of course, the harder your engine works, the greater the risk of this nasty metallic debris, meaning the greater the benefit of using our magnetic sump plug. The MMX Performance magnetic sump plug is crafted from T6-6061 lightweight aluminum and is anodized in our trademark gloss black finish. It's supplied with a set of 5 sealing washers included (additional packs of washers can be ordered). Insist on an MMX magnetic sump plug at your next service! Full OE plug replacement. M18 x 1.5 fitment. Protect and increase engine lifespan. Crafted from T6-6061 lightweight aluminum. Anodized in our trademark gloss black finish. Supplied with a set of 5 sealing washers.

The MMX Performance 90mm billet coolant expansion cap for BMWs has been designed from the ground up in the UK, from a solid piece of billet aluminum. Each cap was designed to directly replace the OE cap, not merely stuck in place. Fitment is for models with the matching OE (17 11 7 639 021) part number.

Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower
