Carbon Performance Intake and 3-Point Strut Brace Kit

We know the G20 and G42 BMW models deliver an incredible driving experience, whether equipped with the B48 or B58 engine. However, we’ve identified key areas where performance and style can be taken to the next level. That’s why we’ve developed the Turner Carbon Fiber Performance Kit, combining our Turner Carbon Fiber Intake System and Turner Carbon Fiber Strut Tower Brace into one ultimate package.

Turner Carbon Fiber Intake System

Upgrade your engine bay with our Turner Carbon Fiber Intake System, designed for maximum performance and style.

Unmatched Airflow: Our intake flows 8% more air than the factory system (445.0 CFM vs. 410.1 CFM), reducing stress on your turbo and delivering optimal performance.
Lower Intake Temps: The enclosed carbon fiber lid reduces intake temperatures by up to 13°F compared to open intakes, ensuring consistent performance.
Premium Materials: Built with a gloss carbon fiber intake tube featuring MAF scaling, a durable 6061-T6 anodized flange, and a wrinkle black powder-coated heat shield for strength and style.
High-Performance Filtration: Includes a conical, reusable air filter with 8-ply oiled cotton gauze and a velocity stack for superior filtration and efficiency.
This intake is the perfect blend of form and function, offering noticeable performance gains while giving your engine bay the high-end look it deserves.

Turner Carbon Fiber Strut Tower Brace

Inspired by the performance-focused "M" chassis, our Turner Carbon Fiber Strut Tower Brace is engineered to improve handling and chassis rigidity.

Enhanced Handling Dynamics: Reduces chassis flex by effectively distributing cornering loads between the strut towers, maintaining consistent wheel alignment geometry during aggressive driving.
Precision Engineering: CAD-designed for a seamless fit with factory mounting points, our strut brace is built with lightweight yet ultra-rigid carbon fiber featuring a 2x2 twill weave.
Durable Construction: Features billet aluminum mounts machined from 6061-T6 aluminum, type II anodized, and securely bonded to the carbon fiber for uncompromised strength and stability.
Striking Aesthetics: Our high-gloss carbon fiber design adds a motorsport-inspired look to your engine bay, complementing any BMW enthusiast's style.
Why Choose the Turner Performance Kit?

Performance Gains: Maximize airflow and structural rigidity to make your G20 or G42 sharper, more responsive, and more enjoyable to drive.
Premium Appearance: Transform your engine bay with matching carbon fiber components that deliver both performance and head-turning style.
Easy Installation: Both the intake and strut brace are designed for a straightforward, bolt-on installation using factory mounting points—no modifications required.

We are proud to present you with our long-awaited Turner Motorsport Carbon Fiber B58 Intakes. Like all of our Turner Motorsport products, our B58 intake was CAD-Designed in-house to give you the best performing, most beautiful intake we could possibly imagine for your B58 powered BMW. The best part? Our design seamlessly integrates with OEM ducting and stock mounting locations to give you a simple install and an OEM+ fit and finish. We believe this is the way the B58 engine bays should have come from the factory. It’s time to ditch all that plastic. Our higher flow filter and intake design reduced post filter pressure by 0.2 psi over stock, allowing for gains across the entire RPM range - this reduced pressure drop also results in less stress on your B58’s turbo. Our enclosed intake also lowers your intake temperatures by 13 degrees over running an open intake.

Introducing our Turner Performance Cat-Back Exhaust for your G20 M340! Precision-crafted exhaust that elevates your driving experience with a new level of excitement. Designed with our commitment to performance and quality, this exhaust is meticulously engineered to unleash the true potential of your M340. In tandem with performance and sound, our cat-back exhaust enhances the visual aesthetic with upgraded quad exit exhaust tips that complement the overall motorsport nature of the M340 and replace the fake factory exhaust tips. Upgrade your driving experience with our cat-back exhaust for your M340! Unleash the power, bask in the glorious sound, and turn heads wherever you go.

Using our signature design principles this exhaust is crafted to deliver a deep, authoritative tone that reveals the true rowdy attitude of the M340. Designed to utilize the factory valve control our cat-back provides an exhilarating sound during acceleration without compromising the daily driving amenities. Our exhaust is manufactured of 1.25mm wall T304 stainless steel for superior durability, corrosion resistance, and aesthetics. Designed with the customer in mind it features a straightforward bolt-on installation utilizing factory slip joints and mounting locations and includes are clamps and hardware necessary for installation.

Upgrading the sound:

Our exhaust allows you to turn up the volume and let the B58TU boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B58 if you're not going to upgrade the exhaust? Our signature muffler design allows you to transfer the exhaust valve from your factory system directly onto your new Turner system. The Turner exhaust signature muffler design allows for two flow paths that change both tone and volume. With the vehicle in eco or comfort mode, the valves remain closed, with the closed valves the exhaust system allows the gasses to flow through the muffler toning down the volume and giving a more refined exhaust note. While in driving modes sport or sport+ the valve opens and the flow path changes to a "straight flow path" essentially turning into a straight-piped exhaust for the least amount of restriction and the most amount of B58 sound!

Upgraded aesthetics:

From the factory, the G chassis comes equipped with fake or imitation exhaust tips, our Turner exhaust allows you to remove the imitation tips from the vehicle and sport a set of 4 true exhaust tips giving that upgraded motorsport styling.

How the cat-back is designed:

To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. We replaced the factory components with our full 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep the flow to a maximum! With smooth mandrel bent transitions our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature B58 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Quad 3.5" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.
