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!

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.

Perfect for my dog
Color: Blue Puppy, Size: Medium Size 2
My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!

Pup loves this!
Color: Blue Puppy, Size: Medium Size 2
My pup loves his soccer balls. These are very durable although if you have a dog that doesn't grasp the concept of using the loops/straps to carry it, teeth could puncture it. They are a good value for the money if your dog likes to chase the ball, I get the smaller size ball for my dog (medium dog). They come with a pump but if you have a bicycle pump or a battery operated pump, it will fill much faster. Ours stay outside and even in the winter, they hold up well, just need a bit more air occasionally to keep it pumped up.
