034 Motorsport - Radiator Upgrade - Audi B9 S4/S5/RS4/RS5 & C8 S6/S7 - 034-102-1005.

If you're looking for a high-capacity, all-aluminium radiator for your EA839 2.9TT or 3.0T equipped Audi, the 034Motorsport Radiator Upgrade is for you!

The 034Motorsport Radiator Upgrade is engineered to replace your factory radiator with a larger, all-aluminium radiator designed and manufactured in collaboration with CSF. This upgrade ensures improved coolant capacity and seamless integration with your vehicle's existing cooling system, making it the perfect option for those looking for additional cooling capacity.

If you're looking for a high-capacity, all-aluminium radiator for your EA839 2.9TT or 3.0T equipped Audi, the 034Motorsport Radiator Upgrade is for you! High-performance driving, especially with added power, can push your engine to generate excessive heat that the factory main radiator may struggle to dissipate. This can lead to elevated coolant temperatures, reducing the effectiveness of your vehicle's cooling system and potentially impacting performance.

The 034Motorsport Radiator Upgrade is designed to replace your factory radiator with a larger, all-aluminium radiator, engineered in collaboration with the cooling experts at CSF Radiators. The 034Motorsport Radiator Upgrade utilizes an all-aluminium construction, engineered to be a drop-in replacement for the factory radiator. Featuring a thicker performance radiator core and re-engineered billet aluminium end tanks to improve the efficiency of coolant flow, the 034Motorsport Radiator Upgrade increases the coolant capacity by 40% and increases the overall cooling capacity by 16% as a result!

Not only is it larger, but the 034Motorsport Radiator Upgrade utilizes 65 individual 2-row B-tube technology cooling tubes that carry coolant across the radiator core to help disperse heat, significantly reducing recovery time between pulls! CSF's "B-tubes" are carefully formed and seam-brazed for a stronger, more efficient design than traditional welded "O" tubes. This allows for thinner, lighter aluminium with improved cooling. The seam-brazed inlet increases heat transfer surface area by ~15%, delivering the efficiency of two smaller tubes within the same space.

Additional Cooling Upgrades for B9/B9.5 Audi S4/S5:

When looking to further improve the cooling performance of your Audi B9 S4/S5, consider pairing the 034Motorsport Radiator Upgrade with the Auxiliary Radiator Upgrade Kit, which replaces the factory side-mounted radiator with an upgraded unit from CSF Radiators!

Solid all-in-one
I was pleasantly surprised by how versatile this bikini trimmer is. The 2-in-1 design makes it easy to switch between body grooming and more delicate areas, so I don’t need to keep multiple devices. The trimmer feels lightweight in the hand, but the build quality doesn’t feel flimsy, it has a smooth finish and is easy to grip, even when used in the shower. The blades glide well over the skin without tugging or causing redness, which is something I’ve experienced with other trimmers. I tried it on underarms, legs, and bikini area, and it handled each area differently but effectively. For sensitive spots, it gave a close trim without irritation, and for legs it left the skin smooth enough for daily wear without needing to go over the same area multiple times. The IPX7 waterproof feature really adds convenience because I can rinse the whole unit under water after use without worrying about damage. The dry shave option is equally practical when I need a quick touch-up. Battery life has been reliable so far, and I like that it’s cordless, which makes it easier to use freely. Overall, this trimmer is a solid all-in-one solution for women who want something compact, gentle, and efficient. It’s especially helpful for anyone who values both convenience and skin comfort.

waterproof
This bikini trimmer is a compact, handheld device, roughly the size of a lipstick tube, that operates on a rechargeable battery and comes with a USB charging cable and a protective cap. I have been using this trimmer for a little over a week now as part of my personal grooming routine. I initially picked this item because I was looking for a small, waterproof tool that could be used quickly and efficiently. I appreciate that the body is made out of a smooth, waterproof plastic, which I think makes it easy to clean and feels hygienic for both wet and dry use.

Handy Compact Trimmer
I really like how this trimmer has two functions in one, it makes things super convenient. It’s small and easy to hold, so I can use it on different areas without feeling awkward. I tried it on both legs and underarms, and it gave a smooth finish without irritation. The design makes it easy to switch between trimming and shaving, which is a nice touch. I also appreciate that it’s waterproof, so I can just rinse it clean after using it. Overall, it feels like a simple and practical tool to keep around for quick grooming.
