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.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!

Great buy
Size: 12 Wide, Color: Black Faux Leather
I absolutely love these Amazon Essentials Belice Ballet Flats! They are so comfortable right out of the box and fit my feet perfectly. I can wear them all day without my feet hurting, which is hard to find with flats sometimes. They’re also really cute and go with almost everything I wear. I find myself reaching for them all the time because they’re both comfy and pretty. Definitely a great everyday shoe, especially for the price!
