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.

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

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King(20"X 36"), Color: Navy Blue, Size: 2 Pack King(20"X 36")
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed) ⭐ The Good • These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric. • The fabric feels slick and cool, but you don’t slip off of it. • They feel cold to the touch right out of the package (which is wild). • I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head. • I’ve honestly never slept this well in my life. • For the price, you cannot beat them, and they go on sale often. • These beat any high-end version I’ve tried. • If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these. ⚠️ The Bad • The fabric does show crease lines. • If wrinkles bother you, this might annoy you (doesn’t bother me personally). 🔧 What I’d Change / Tips for Care • Don’t use fabric softener — it clogs the cooling fabric and ruins how it works. • Wash with unscented detergent + a little vinegar. • Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term). ✅ Final Thoughts I will literally never not own these again. If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it. 10/10 recommend.

Love it but it stains
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.

Silky and Soothing
Color: Cream, Size: 2 Pack Queen(20"X 30")
I thought I was getting 1 of the queen sized but I got 2. I got these for my Pomeranian's fuzzy pillow. He's always hot and these are very cooling and very good quality. He loves them and are very comfortable for him. They totally transformed his shaggy old pillow. I used the larger body pillow covers to replace the covers I had. They matched my bedspread perfectly. I use 2 body pillows along the exterior wall in my bedroom where there is cold coming through the floor in the winter. I'm sure I will enjoy them in the summer when it's hot too!

So soft and amazing quality
Color: 12 - Light Beige, Size: Twin
I can't tell you if they're cooling or not yet. The weather took a turn for the cold so I haven't put them on the bed yet. But the quality..omg it's exceptional! These are insanely soft! Not slippery like satin but not scratchy like percale. They're like the best of both worlds..light as satin but nicely weighty like percale. I don't know what kind of sorcery this is but these are literally better than those 6-zillion count Egyptian cotton sheets that cost more than the GDP of a small nation. These are exceptional!! Soft as butter but still feel like they'll last a while and not let you fall out of bed like silk lol. When you fold them, they snap nicely. They seem to have a lived in look..like they'll never be utterly wrinkle-free but who cares..they're smooth, soft and supposed to be cooling. I never thought I'd find anything more comfortable than cotton sheets but these are even better. The colors are ok. Pretty basic but they are true to life..some others look different online than when you get them..not these colors online are accurate. This was a great deal and I'd recommend a thousand times over!
