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!

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!

The Dog LOVES IT!
I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!

My Golden Retriever’s favorite
We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.

doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.

Blue ball, my dog likes blue.
Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼‍♀️
