034 Motorsport - X34 Carbon Fibre Cold Air Intake - BMW B58 F Series M140/M240/M340/M440.

034Motorsport's X34 Carbon Fibre 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 UNNECESSARY 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.

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out! It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy. The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement. The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort. It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using. Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion. The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home. As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months. Overall, this suit offers exceptional value for the price.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
