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.
This is a list of components needed to retrofit the 034Motorsport Auxiliary Side Mount Radiator Upgrade Kit. This list is specifically for vehicles that are not equipped with the factory driver’s side auxiliary radiator.

We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
