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.

Sturdy
The ball bearings make them roll smooth. I've put plenty of pressure through them and no bending or breaking. The middle sized unit is probably the most useful. The small one has it's uses but can act like a pizza cutter and easily go through sound deadening mats. The large one has a little too much surface area to get a good crush on the mats.

Works great, good price
Makes installing sound deadening panels a breeze. A little elbow grease required but makes for perfect contact with the sheet metal and butyl.

Well Made Tools!
I have been installing Kilmat in my early 74 Datsun 260Z restoration and these tools are very nice for the price. I like them because they actually have ball bearings and move smoothly over the matting. The size selection is very handy as well and even has some nice finished wooden handles.
