HP Gain: +13hp
Trq Gain: +13ft-lbs
Airflow: +28% over stock

aFe has engineered the Momentum GT intake to outperform the stock air box and deliver substantial power and torque gains over the factory system. The B58 3.0L Turbo benefits from aFe's oversized cotton filter element in a Rotomold plastic housing that blocks heat saturated air while flowing more volume of cooler dense air. The system has been CAD designed to achieve the maximum volumetric flow rate into the turbo. The intake tube is a smooth, unobstructed single piece from the air inlet to the airbox and incorporates a port for the air flow sensor. aFe's advanced engineering and design have made this a direct bolt-in intake upgrade.

The aFe filter has been designed specifically for this application and uses aFe's high flow/low maintenance design. The ProDry S filter has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe Pro5R filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

 Founded in 2003 Seibon Carbon excels in delivering premium quality carbon fiber products to those with discerning tastes. The process begins with the best carbon raw material manufactured in either USA or France; in fact it is the same stock that can be found on high performance racecars, battleships and satellites. Supporting race teams is one of Seibons' specialties and you will see their work in many different platforms and racing types. Drivers such as Michele Abbate in her Scion FRS racecar, Fredric Aasbo in his Formula D Scion tC and even team RS-R in Asian Formula D all rely solely on Seibon to get them to the podium.

Using single piece construction, the carbon is laid inside of a mold instead of being wrapped around it. This allows for a much stronger piece in the end and allows much greater control when the resin is applied. Areas such as door hinges, hood latches and window regulator mounting points are reinforced so as to add strength and longevity through repeated use. Application of the resin is then accomplished using proprietary techniques that allow for a much more uniform coating than most competitors and yields a product that is lighter, since there is no excess.

Finally the product is finished with a glossy clear coat this resists chipping and cracking and gives a glossy wet look. Inspection of the finished product is then performed to ensure there is no weave distortion in tight corners or complex bends.

Features:

• Proprietary methods to lay wet carbon for a stronger and lighter product
• UV resistant resins, even a weathered part can be wet sanded and brought back to original finish
• Panels are 70% lighter than stock as opposed to competitors which come in around 50% lighter than stock.
• No black paint is used to hide imperfections along detail edges and creases.
• Partnered with SCCA and Formula Drift bringing their top quality fit and finish to the competition environment.

This item fits the following BMWs:
2012-2017 BMW F22  228i 228iX 230i 230iX M235i M235iX M240 M240iX

Direct replacement REAR brake rotor for F30 320i/328i and F32 428i (RWD models) and F33 428i/428iX convertibles (with N20 engine, not N26 SULEV).

Zimmerman rotors are finished with an anti-corrosion zinc dichromate coating over the entire rotor. This coating is applied over the rotor hat, face, and through the vanes for total corrosion protection. Even after a year of use the Zimmerman coating doesn't change color or effectiveness. The rotors are ready to use after correct bed-in procedures have been done. In addition, Zimmerman uses a high carbon content in their discs for improved thermal performance.

Price is for a pair of rotors.

This item fits the following BMWs:
2014+ F22 BMW 228i 228iX
2012+ F30 BMW 320i 328i - Sedan
2014+ F32 BMW 428i - Coupe
2014+ F33 BMW 428i 428iX with N20 engine only - Convertible
N20 engine: the rear rotors were different on the F33 428 convertible based on which engine the car has. N20 is the ULEV engine; N26 is the SULEV low emissions engine. The emissions sticker under the hood will be labeled ULEV or SULEV.
Application note: these rotors fit cars not equipped with the factory M Sport package or M Sport brakes upgrade

For over 30 years, Active Autowerke has been the one to turn to for high-quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. 

The B46 downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory downpipes – therefore reducing radiant heat and increasing performance.

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers. 

Charge Air Cooler Expansion Tank - Rein | BMW F22/23, F3X B48/B46 B58 is an essential component that ensures proper coolant circulation in the charge air cooling system. Acting as a reservoir, this expansion tank allows coolant to expand and contract with temperature fluctuations, preventing excessive pressure buildup. Over time, plastic tanks can become brittle due to constant exposure to heat cycles, leading to cracks and leaks. A failing tank can cause coolant loss, reducing the efficiency of the charge air cooler and leading to increased intake temperatures, which negatively impact horsepower and engine performance. Rein offers a high-quality direct replacement designed for durability and a perfect fit on BMW F22, F23, and F3X models with B48, B46, and B58 engines.

• Maintains proper coolant circulation within the charge air cooling system
• Prevents excessive pressure buildup caused by temperature fluctuations
• Durable construction resists cracking and leaks for long-lasting performance
• Direct replacement for BMW F22, F23, and F3X models with B48, B46, and B58 engines
• Helps maintain optimal intake air temperatures, preserving horsepower and efficiency
• OE-quality fitment ensures hassle-free installation and reliable function
