If you drive your B9/B9.5 S4/S5 on track or hard on backroads, or simply during daily commutes in hot climates, the 034Motorsport Auxiliary Side Mount Radiator Upgrade Kit is the perfect upgrade to help regulate and maintain optimal engine coolant temperature. While high-performance driving can push your engine to higher coolant temperatures, doing so with added power can generate excessive heat that the factory side-mounted radiator can struggle to dissipate. This can lead to elevated coolant temperatures, reducing the effectiveness of your vehicle’s cooling system and potentially impacting performance.

The Auxiliary Side Mount Radiator Upgrade Kit is designed to replace your factory side mount radiator with the larger and more efficient CSF Radiator. This upgrade increases cooling capacity and enhances the reliability of your cooling system. Whether you’re looking to tackle backroad and track adventures or live in a higher-temperature climate, this upgraded side mount radiator provides the cooling performance you need to keep your engine running at its best, lap after lap, mile after mile, regardless of the ambient temperature!

The Auxiliary Side Mount Radiator Upgrade Kit is designed specifically as an upgrade for vehicles equipped with the OE auxiliary radiator, ensuring compatibility and seamless integration with your vehicle’s existing cooling system. Before purchasing, please inspect your vehicle to see if it is equipped with the factory driver-side auxiliary radiator. You can do this by opening your hood and visually identifying this factory auxiliary radiator that lives in the front driver-side fender well underneath your headlight. If you do not have the factory driver-side auxiliary radiator, you can easily retrofit the necessary mounting provisions and hoses to install the Auxiliary Side Mount Radiator Upgrade Kit utilizing the OEM components listed below.

034Motorsport Engineers extensively tested the Auxiliary Side Mount Radiator Upgrade Kit on 034Motorsport's Development B9 S4s on backroads and at multiple racetracks and found it to greatly improve the cooling capacity over the factory auxiliary side mount radiator.

My Dog Is Obsessed With This Toy!
Color: Orange, Color: Orange
My dog absolutely loves this toy and plays with it every day. The moving and rolling action keeps him entertained much longer than regular toys. He loves chasing it around the house and tugging on the rope. It’s also nice because it helps burn off some of his energy indoors. The material feels pretty sturdy, and charging was easy. Definitely one of the best interactive toys I’ve bought for my dog!

Waste of Money
Color: Orange
Cool toy but my dog ate through it the second day he played with it. It is not for strong dogs. No durability. I had to throw away the orange covers and now he just throws it around.

Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.

Must get!, Great interaction, mind stimulation
Color: Orange
Love this my pup can't get enough. My pup loves this and is hard on it. She throws it all around chases it and guards it like it is her child. It is strong, sturdy easy to charge and fun to watch her engage with it. Definitely must have and I will buy more. It shakes and rolls around, it walks itself and engages the pup to chase. The design is spectacular. It is light weight and the noise level is typical of a toy engaging response.

Awesome for hyper dogs
Color: Blue
AWESOME - I have a dog that just won't stop trying to get me to play with him ALL day! I turn this thing on and he goes nuts and tires himself out...without any help from me. The cover got torn off and torn up in minutes but he doesn't care. He just wants this ball. My other dogs, who are older, aren't really interested. But if you have a hyper dog this is the thing for you and them!
