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.

A must have for your summer bag
I am 100% devoted to Blue Lizard products! I got some extra sun and needed relief, fast. This non-greasy nor slimy cream is exactly what I didn’t know I was looking for. I had applied aloe alone to my skin and received no relief. Within minutes if not seconds of applying this, I had noticed improvement. The consistency is not too thick or too thin, it absorbs into the skin nicely and can be reapplied without getting cakey. It gave my sunburn relief while also moisturizing the skin. I haven’t peeled at ALL. I love that it has clean ingredients and a neutral fragrance. My skin is so sensitive, so having natural ingredients is a plus. Blue Lizard After Sun is now my holy grail and I will recommend it over and over.

HANDS. DOWN. AMAZING.
I have used other products for after sunning in the past. This stuff is AMAZING and I wish I could be a spokesperson for it. I am extremely fair skinned and used this on my vacation at the beach. I used some spf which always leaves me slightly red. I put this on every night and the redness was gone by morning! I was ready to hit the sun again! It doesn’t have a scent and doesn’t leave a sticky lingering feeling or weird smell either. Just moisturizing and safe for my acne prone skin. I will buy this and use this forever!!!!

Phenomenal.
Got a baaaaad sunburn from head to toe. On day 2 or 3, I finally got this stuff. It took the sting away quickly. No smell, and it feels nice on the skin. It’s thin and spreads well. Definitely helped keep my burns moisturized - I didn’t even peel, save for the blisters on my shoulders. My boy even let me put it on his pink little cheek, and

Miracle in a bottle!
This was a lifesaver, I got badly burnt just walking for several miles one day. It was only in the 80's, not 100 degree's but still hot. Where I live there is a poor air quality, too. I was red as a lobster! It was painful and then i saw this. Read the reviews and hoped it would help. Did it ever! It not only helped sooth my skin, calm it down, it dramatically reduced the redness in just a few days! I should have saved the photo's of the before a several days after, but I deleted them. (I wasn't thinking and they were kind of gross). They would have shown the extent of the healing thanks to this cream. I even had some blisters, that shrank in two days after applying this! By the fourth day of applying this cream, they were gone and my skin went from being deep red to pink. What is even more awesome is this moisturized my skin! I have sensitive skin and this did not irritate it. So that was a plus! My only issue was it's a little tacky, sticky after you apply it. So don't apply right before bed, unless you want to be stuck to your sheets. If you're in dire need of relief and to reduce the redness, this is what you want, it is a miracle in a bottle!

Good sunscreen
I originally had purchased the spray version of this product. Unfortunately, the cans clogged so I needed to return them and I ordered this instead. It tends to go on thick but I really need heavy protection so it’s fine. Seems to give good protection and I will buy it again. I’m only giving up four stars because I would’ve preferred the spray.
