034 Motorsport - X34 4" Carbon Fibre Closed-Top Cold Air Intake System Audi TT RS & RS3 (8V/8S/8Y) - 034-108-1041.

034Motorsport is pleased to present our X34 4inch Carbon Fibre Closed-Top Cold Air Upper Intake System for the 2.5 TFSI EVO engine found in the 8S Audi TTRS and 8V.5 Audi RS3!

034Motorsports engineers spent extensive effort to develop a cold air intake solution for the TTRS and RS3 that yields horsepower and torque gains over the well-designed factory airbox. During the development process, many iterations were designed, prototyped, and tested, which resulted in this beautifully-manufactured Carbon Fibre Cold Air Upper Intake System.

Designed For Modularity

034Motorsport engineers dissected the factory intake system, and identified the key weak points that it had for high performance flow. During this dissection, it was found that the largest restriction was the filter membrane, and the accompanying plastic accordion hose that runs to the turbocharger. The factory lower air box and fresh air duct, however, with some modifications, were found to be suitable for most stage 1 and stage 2 setups.

This drove the modular design that the X34 Evo intake systems all share, where the upper air filter system can be used both with the factory lower airbox and fresh air duct, and with the 034Motorsport X34 lower intake box and fresh air duct. This allows for the end user to purchase individual components to eliminate the largest flow issues, while still having a path to upgrade to higher flow and performance.

Maximizing Airflow

034Motorsport engineers first created a CFD-optimized carbon fibre intake tube, which is a direct, high-performance replacement for the plastic factory accordion 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 turbo inlet.

Minimizing Intake Air Temperature

To ensure that the 034Motorsport X34 Closed-Top Cold Air Upper Intake System draws in cool, dense air, the system includes a fully enclosed carbon fibre heat shield to replace the upper airbox as well as a stainless steel heat shield to block heat from saturating the intake tube. The upper carbon fibre heat shield bolts to the factory lower airbox, allowing the high-flow conical filter to breathe cold air from the factory inlet duct before the radiator. The stainless steel heat shield bolts to the stock intake tube mounting point and to the back of the head, preventing the high temperatures from the exhaust header and turbo from radiating directly at the intake tube. Both heat shields work together to minimize pre-turbo intake air temperature.

4" Diameter For Maximum Performance

034Motorsport engineers identified a serious bottleneck in the factory intake system. The factory, 2.8 inch turbo inlet size, which necks down even smaller throughout the unit, is by far the largest restriction in the intake system after a performance filter system is installed. Many aftermarket companies, including 034Motorsport, have solved this issue by increasing the turbo inlet diameter, thus warranting an intake that supports the added flow gain. The 4 inch diameter intake kit is designed to support upgraded 4¢‚¬ turbo inlets that can be used on factory, hybrid, and full frame turbochargers. It has been validated that this intake works with the majority of aftermarket inlet options, but has been optimized to work with the upcoming 034Motorsport 4 inch 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 air filter size without taking into account the detrimental effects of shrouding the filter.

Performance Air Filter

The 034Motorsport Carbon Fibre Closed-Top Cold Air Intake system houses a high-flow conical air filter with double-layer pleated cotton filtration medium. This air filter design offers increased flow through an enlarged filtration surface, while ensuring superior filtration.

OEM+ Fit & Finish

034Motorsport carefully selected the carbon fibre weave on the intake tube and upper airbox heat shield to match the factory carbon fibre engine trim found in the Audi TTRS & RS3 2.5 TFSI engine bay. The 034Motorsport Audi TTRS & RS3 4 inch Cold Air Upper Intake System was designed to fit like a factory part, and mates directly to the turbo inlet pipe and factory lower airbox to provide an OEM+ look.

Dyno-Verified Wheel Horsepower & Torque Gains

034Motorsport's engineering and development efforts were validated on multiple vehicles using our Mustang AWD Dynamometer to ensure that the 034Motorsport Audi TTRS & RS3 4 inch Closed-Top Cold Air Upper Intake System provided substantial increases in horsepower and torque on both stock turbo vehicles and ones with upgraded turbo kits alike.

Excellent chair/great support.
Color: Black Full Mesh, Style: Executive
Excellent, comfortable chair! I was surprised at how easy it was to assemble---but the directions were super clear and all the pieces and parts were labeled. Once I received the chair, I was also surprised with the email follow up from Alice at Molents. All this for a reasonably priced chair.

Great Ergonomic Support and Fit, with Minor Adjustment Caveats
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
As someone who is 5'4" and 140 lbs, the size of the chair feels ideal, and the seat cushion is spacious without feeling overwhelmingly large. The breathable mesh material is high quality, keeping me cool during long working sessions while still feeling sturdy. The back support and adjustable lumbar feature aligns perfectly with my spine and has noticeably reduced my posture fatigue. The height adjustment mechanism operates smoothly to align perfectly with my desk, and the assembly process was surprisingly straightforward, taking less than 20 minutes with clear instructions and tools included. My only slight hesitations are regarding armrests not being long enough. The wheels are not easy to roll on carpet and require a bit of extra effort to move. Maybe a chair mat might be helpful on carpeted floors. However, for the price, the comfort and build are impressive.

High quality and incredible customer service
Color: Black Full Mesh, Style: Executive
This is an extremely well made chair at a very competitive price. The packaging, assembly instructions, as well as the way the hardware was packaged and labeled is probably the best I've seen. I'm particular about tools, and the included allen wrench was better than the normal "included tools" so much so that i actually used it rather than one of my own. The assembly was easy, and the chair itself looks and feels very high quality, and is very comfortable. Perhaps best of all was the level of customer service. I emailed on a weekend to activate the warranty and request the free cushion they offer. I got a personal response in less than a day and they offered upgraded wheels for free as well. This is a company worth doing business with.

Great product AND customer service!
Color: Black Full Mesh, Style: Executive
I'm having a hard time writing this review because I can't tell which one I like better: the product or the customer service! I work on a computer all day, so a comfortable office chair is critical for me. This chair is great - it's adjustable in every way I need it to be, especially the armrests. The breathable mesh is both durable and supportive, and is more comfortable to sit in than the "overstuffed" chair it replaced. Let me just say: no company provides better customer service than MOLENTS. Right after assembling my chair (which was very easy, btw), I registered for the 2 year warranty they offer. The NEXT DAY I received an email from Alice in their customer service department 1) to confirm my warranty, 2) to tell me about the free foam seat cover they were sending me, and 3) to make sure the chair was comfortable and easy to assemble. Very few companies take the effort to follow up with customers right after making a purchase like that. I'm extremely happy with this purchase. This chair is worth MORE than it's weight in gold, and I strongly recommend to anyone thinking about buying an office chair to buy it from MOLENTS - you won't regret it. Oh, and if Alice's supervisors are reading this: she absolutely deserves a promotion!

Great value and a good chair
Color: Black Full Mesh, Style: Executive
Great chair for the price. Not as solid as an Ergo but it's not thousands of dollars either. It's pretty easy to assemble and the directions are good. It rolls well on LVP flooring and they offer 'upgraded' wheels at no cost from what I can tell. I didn't order them since the included ones work perfectly. I'm 6'4" and both the seat and arm heights can be adjusted to fit me well. The mesh seat is comfortable and the back works fine. The only downside for me is that the lumbar support doesn't adjust quite high enough to actually reach my lumbar area, but I think it would work for most folks. Overall it's hard to argue with the cost and even if it only lasts a few years it's worth the money.
