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.

Clean Ingredients & Leaves Teeth Feeling Smooth
Size: Pack of 1, 4 Ounce, Set name: B. Whitening
I’ve tried many natural toothpastes, and this one quickly became a favorite. The texture feels smooth, and my teeth feel really clean after brushing. I love that it contains nano hydroxyapatite and is fluoride-free, especially for sensitive teeth. The flavor is fresh without being overpowering, and it doesn’t leave a weird aftertaste. It’s also gentle enough for everyday use and makes my teeth feel polished and healthy. Definitely worth trying if you want a cleaner alternative toothpaste.

Perfect Fluoride alternative
Size: Pack of 1, 4 Ounce, Set name: B. Whitening
I bought this because it's popular in other countries like Japan. America is so behind using fluoride, when it's been proven to cause pituitary gland problems. If you're looking for a fluoride-free toothpaste look no further. It works well, you just unscrew and apply to your brush. Pro tip: use a sonic toothbrush and glide on your teeth at a 45° angle. Using this toothpaste for months, 2 minutes twice a day, has made my teeth visibly whiter. The flavor is not super strong, so it's suitable for kids and really anyone. Super easy and simple to use, it works like regular toothpaste. Smells minty, it's fluoride-free, and medium sized. It'll last me about 2 months, which I find worth it.

Fluoride who?
Size: Pack of 3, 4 Ounce, Set name: B. Whitening
Great product definitely works better than your traditional fluoride or fluoride free toothpaste it actually combats plaque and strengthens the enamel of your teeth I have physically and visibly seen the difference not just in my teeth but gums. Tastes great cleans well clean ingredients the only downside is it's unfortunately very pricey and if you're buying for not just yourself but a family it can start to add up fast just something to consider before purchasing. I love the tube and cap design it's gentle on your gums and teeth and it has good ingredients making the minty flavor taste more natural rather than a synthetic mint flavor and this product actually whitens your teeth. keep in mind that this isn't a replacement for teeth whitening treatments and it's also not a replacement for good dental hygiene like flossing/brushing multiple times a day. If your suffering from serious Dental issues this will not cure it but it is an excellent alternative to fluoride toothpaste that provide little to no benefit for your actual oral and overall dental health. The reason for four not five stars is because of the price I think if they could continue making the same product got the same level of quality for a little less money it would be a five-star item

URGENT!!!! REALLY WORKS!!!! Fact ✔️
Size: Pack of 3, 4 Ounce, Set name: B. Whitening
I was immediately convinced this would work due to its ingredients, I had a previous filling fallout. So I immediately requested he apply another filling while I was getting some other dental work done, and the dentist said there was no rush to install, A new filling, showed me a picture. It looked great still white no cavities. In the high definition, microscope photo he showed me,It almost look like the inside of a white Jacuzzi tub with molded seat, I had the rest of the work done and didn’t get to go back soon enough, and the tooth started to bother me when something sweet would hit that spot and I looked in the mirror and it was starting to turn a light brownish color, I had just heard about HA toothpaste, I did some research and this is what I found Hydroxyapatite = the SAME mineral your teeth are made of • Your enamel is mostly this material (like 70–97% of tooth structure)  • So instead of adding a chemical… it’s literally rebuilding with the original material When you brush with nano-hydroxyapatite: • Tiny particles fill in microscopic cracks in enamel • Helps reduce sensitivity • Can make teeth look whiter naturally (smoother surface reflects light better) • Strengthens teeth against future damage so I ordered 3 pack Boka HA and on everything I love in three days of brushing for 2 minutes twice a day morning at night, do not brush your teeth with tapwater ever!!! It has more chlorine than a swimming pool, calcium lead, and other harsh chemicals that will take away the layer it’s going to build always use bottled water and do not rinse this toothpaste out of your mouth. Let it settle in and pack it into your molars and in between your teeth,it was completely healed and no sensitivity to sugar, hot or cold, it tastes great, and the fluoride free is the only way to go fluoride will destroy your tooth enamel, I gave the other two tubes to my kids and they love it, I am looking forward to less dental appointments for sure!!!!!

Five stars for BOKA without hesitation.
Size: Pack of 1, 4 Ounce, Set name: A. Ela Mint
I have tried a lot of natural toothpastes over the years and I can honestly say that Boka completely surprised me in the best possible way. From the very first use it felt like I had finally found a toothpaste that balances modern science with a clean ingredient philosophy. You will not be disappointed. The standout ingredient here is nano hydroxyapatite, which is the same mineral that naturally makes up tooth enamel. That immediately caught my attention because instead of simply masking dental issues it actually supports remineralization. After learning more about nano hydroxyapatite and how it interacts with enamel I felt confident giving this toothpaste a real trial. The texture is smooth and creamy and it spreads easily across the teeth. Some fluoride free toothpastes can feel chalky or thin but this one feels refined and well formulated. It produces a gentle foam that feels pleasant while brushing but never overwhelming. The flavor is another area where this toothpaste shines. It is refreshing without being harsh or overly minty. My mouth feels clean and balanced after brushing rather than blasted with artificial intensity. That subtle freshness actually lasts much longer than I expected. After about two weeks of consistent use I started noticing that my teeth felt smoother throughout the day. That polished feeling you normally get right after a dental cleaning lasted longer than usual. My teeth also appeared brighter which was a welcome bonus. Another thing I appreciate is the ingredient transparency. There are no questionable additives and it is completely fluoride free which is important for people who prefer alternatives that still support enamel health. Knowing that nano hydroxyapatite is widely used in advanced dental care products in other parts of the world made this even more compelling. The packaging is clean and modern and the tube dispenses easily without making a mess on the cap. It feels like a premium product from start to finish. What really impressed me is how well this toothpaste balances effectiveness, comfort, and thoughtful formulation. It manages to feel gentle while still leaving my teeth incredibly clean and refreshed. If you are looking for a high quality fluoride free toothpaste that focuses on enamel support and a healthier approach to oral care then I highly recommend giving this one a try. It has absolutely earned a permanent place in my daily routine and it is one of the few natural toothpastes I genuinely look forward to using every day.
