BMW Strut Braces & Stress Bars for BMW 4 Series G22 (2021+)

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.
