034Motorsport's X34 Carbon Fiber Cold Air Intake System delivers improved power, sound, and acceleration to BMW F2X/F3X B58 owners in a clean OEM+ package.

Through extensive evaluation of the factory airbox design, 034Motorsport's engineers were able to create a performance replacement that allows for increased airflow to the turbocharger and engine. The X34 Carbon Fiber Cold Air Intake System offers measurable performance improvements, simple bolt-on installation, and unsurpassed fit and finish.

034Motorsport has developed this comprehensive performance intake solution for the BMW F2X/F3X B58. Subsequently, the X34 Carbon Fiber Cold Air Intake System offers discerning enthusiasts measurable increases in horsepower and torque, sporty induction and turbocharger sounds, and a beautiful carbon fiber airbox design.

Throughout the development process, multiple designs were modeled, prototyped, and tested - all to ensure that the X34 Carbon Fiber Cold Air Intake System delivers measurable performance benefits and superb fitment. The X34 Carbon Fiber Intake System utilizes a partially-enclosed airbox that uses the factory fresh air inlet duct and heat shield that houses a 3.5" inlet conical air filter. This filter is mounted to a CNC-Machined Velocity stack, which smooths the airflow and increases air velocity, allowing for even more airflow through the matching CFD-optimized filter tube to the turbo inlet.

Minimizing Unnessary Filter Shrouding:

034Motorsport focuses on optimizing every aspect of the intake system across a broad range of variables and compromises. A critical component of a high-flowing performance intake is the ability for air to flow around and into the filter. If the air cannot flow freely around the filter, it will be restricted from getting into it. Many aftermarket kits fit too large of a filter in an enclosure that cannot accommodate its size, thus choking the filter and reducing its overall flow. This often happens when a product is engineered for one variable at the expense of others.

034Motorsport conducted extensive tests and refined its development of the intake design to allow for maximum airflow surrounding the air filter, allowing for optimal airflow to, and through, the filter. The final result is the right size filter in the right size filter housing, creating maximum airflow and performance with OEM level filtering, the ultimate goal of any intake system. Be cautious of any intake that brags only of the air filter size without taking into account the detrimental effects of shrouding the filter.

Maximizing Airflow:

034Motorsport engineers first created a CFD-optimized 4-Ply silicone intake tube, which is a direct, high-performance replacement for the plastic factory accordion/sound deadening hose. Using CAD software and 3D scanning technology, 034Motorsport was able to optimize the cross-sectional area of the intake tube while being mindful of space constraints. The resulting part is a functional work of art - maximizing performance given the factory space constraints and featuring smooth transitions that ensure optimal airflow to the throttle body.

Performance Air Filter:

The X34 Carbon Fiber Intake houses a high-flow conical air filter with a double-layer pleated cotton filtration medium, capable of trapping particles as small as 5 Microns. This air filter design offers increased flow through an enlarged filtration surface while ensuring superior filtration. We have tested this air filter in applications over 800HP with minimal restriction and superior OEM quality air filtration.

While many intake kits leave the air filter unsupported and ”flopping” around, 034Motorsport engineers designed a clever air filter support that not only prevents unwanted movement but also allows compliance to accommodate engine movement under varying load conditions. An added benefit is an air shroud that doesn’t move and rub on other engine compartment components like many other designs on the market do.

CFM Gains:

CFM stands for "cubic feet per minute" of airflow. The higher the number, the higher the horsepower an intake can support. At 034Motorsport, we design our intakes to have substantial flow increases over the factory intake, and we test all our intakes at 28" of water (how much vacuum is used to suck air through the intake) on a Superflow airflow bench which gives us very accurate and repeatable test results. A stock intake that flows 200CFM may only freely support about 300HP. An intake that flows 400CFM can support roughly twice that power or 600HP.

• Stock Intake Intake: 674 CFM @ 28in H²O
• X34 intake: 814 CFM @ 28in H²O
