If you drive your B9/B9.5 S4/S5 on track or hard on backroads, or simply want to ensure your EA839 3.0T stays cool no matter the temperature outside, the 034Motorsport Auxiliary Side Mount Radiator Upgrade Kit is the perfect upgrade to help regulate your engine's coolant temperature.

The 034Motorsport Auxiliary Side Mount Radiator Upgrade Kit includes everything you need to replace your factory side mount radiator with the larger CSF Radiator. The Auxiliary Side Mount Radiator Upgrade Kit is designed specifically as an upgrade for vehicles equipped with the OE drivers-side 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.

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!

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.

Game-Changer for My Space!
Color: White, Size: 4 Panel Basic
I recently purchased the Kecreque 4-Panel Room Divider, and it has completely transformed my living area. At 88" wide, it provides ample coverage, creating a private nook in my open-concept home. The white polyester fabric is not only sleek and modern but also wrinkle-resistant and easy to clean—just a quick wipe with a damp cloth, and it looks brand new. Assembly was a breeze; I had it set up in about 20 minutes. The metal frame feels sturdy and durable, and the three extra-wide metal feet offer excellent stability, ensuring it doesn't tip over easily. I love how the panels are connected with flexible buckles, allowing me to adjust the configuration to suit my needs—be it a straight line or an angled setup. This divider has been perfect for creating a dressing area in my bedroom, and I've also used it to section off a workspace in my living room. Its versatility is unmatched, and it folds down compactly when not in use, making storage hassle-free. If you're looking for a stylish, functional, and easy-to-use room divider, I highly recommend this one. It's been a fantastic addition to my home!

Sturdy and Functional
Color: White, Size: 4 Panel Basic
I got this to replace a poor quality divider that I tried first, and this thing is the best! It is easily folded, stands sturdily, easy to assemble, and the fabric looks great. Very very happy with the quality for the price.

Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed but it could’ve been a fail and a returned product
