PRODUCT INFORMATION
Rear Duct
*Now made of high-quality Kevlar Carbon!*
The brakes on the rear axle are subject to enormous heat on BMW models!
On racing vehicles, Speed Engineering were able to determine that the inside of the brake disc (despite the brake upgrade) on the rear axle builds up extreme temperatures. Apart from the high temperature development, an extreme difference between the inner and outer side leads to an uneven wear pattern on the brake pads.
The Speed Engineering solution is a plug & play upgrade and does not require any adjustments to the vehicle, no installation of a hose, clamps or other accessories making a wear-free system. The original screw points/forms on the wishbone are used for attachment.
The air is fed directly into the inside of the rim via a flow channel.

Convenient, Compact, and Powerful – A Must-Have for Any Setup
Size: 5 FT (2 prong plug), Color: White
This power supply is a total game-changer for keeping everything charged and organized. It has a solid number of AC outlets and multiple USB ports (including fast-charging), it is great for charging laptop, phone, tablet, and other gadgets all in one place without a mess of adapters. I use it in my shop to charge pool robots, rechargeable lights batteries for my hand tools and outdoor tools. The USB ports makes it great for charging items that come with a USB cord, no need for an adapter.
The build quality is excellent—sturdy casing, decent cord length, and no overheating even with several devices running at once. I also appreciate the smart layout: the plugs are spaced far enough apart to handle bulky chargers, and the USB ports work reliably.
Great for a home office, bedside setup, or travel. If you’re tired of rotating devices in and out of a wall plug, this is well worth the purchase.

Got the job done!
Size: 5 FT (2 prong plug), Color: White
This was the perfect solution. Old outlet and the single plug didn’t overly strain the wall socket. Lots of plug-ins for all our electronics and a long enough core to reach them all.

Lots of nice features
Size: 5 FT (2 prong plug), Color: White
664Very nice. Even the slots on the sides will enable a larger than expected plug. Wish they included the screws for mounting. Didn't think it would be a big deal as I always keep the extras from projects, but it would have been a nice touch. If you do mount the power strip, it does reduce the size of the plug it will accommodate on the sides. Also wish I would have purchased the longer cord- NOT the fault of the product. Love the flat angled plug! I'm using it behind an adjustable bed frame that moves several times a night, so knowing I won't accidentally knock it out of the wall is nice. And you can easily use both wall plugs. Also very convenient to connect the USB & USB-c plugs without the bricks.

Works perfectly for what I needed
Size: 5 FT (2 prong plug), Color: White
We have an older house and I needed a 3 prong plug in our living room and this has absolutely done the job. I love that I can now plug my computer in and as a bonus, I can charge my phone if needed. The cord link is longer than I needed for the living room but worked great for a recent trip.
