034Motorsport Auxiliary Side Mount Radiator Upgrade Kit, B9/B9.5 Audi S4/S5 3.0TIf 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.

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.

Nice Suit For The Price
This suit was a time-saver! My wife ordered a tux that wasn't going to make it for a formal occasion, so this was ordered and came within three days. It was a good thing she purchased 2, in case of sizing errors. The extra large pants worked, but sizing down to the large jacket & vest made the best combination/fit. We didn't go with the blue/black bow tie & flower it came with, but may for another event. However, being able to work interchangeably at a low price was rewarding!! Thought to add comments that the look of this suit is pleasing (though it's not the best thread). The workmanship gives it a 5 and even greater. The compliments were many. I do suggest using a good steam iron that will eliminate the wrinkles, without creating unwanted creases, while barely touching the suit; but, definitely follow the creases in the pants leg.

Disappointed
Size: XX-Large, Color: Light Grey, Size: XX-Large, Color: Light Grey
Overview of the Purchase Experience I recently ordered a 3-piece suit for my significant other, who is quite tall at 6’8”. I was excited about this purchase, hoping it would be a stylish addition to his wardrobe. However, upon receiving the suit, I encountered several issues that I feel compelled to share. Color Discrepancy One of the most disappointing aspects of this order was the color inconsistency. The suit was supposed to be a cohesive set, but it arrived with two different colors. This mismatch not only detracted from the overall aesthetic but also made it difficult to wear as a complete outfit. When purchasing a suit, especially a three-piece one that includes trousers, a vest, and a jacket, one expects all pieces to match in color and style. Unfortunately, this was not the case here. Quality Concerns In addition to the color issues, I found the quality of the fabric and construction to be subpar. The material felt cheap and did not have the durability or elegance one would expect from a suit. The stitching appeared uneven in places, and there were loose threads that raised concerns about its longevity. A well-made suit should exude quality and craftsmanship; however, this product fell short on both counts. Fit Issues Related to Height Given my significant other’s height (6’8”), finding suits that fit well can be challenging. While I cannot recall his exact weight at this moment, it’s important to note that tall individuals often require tailored fits or specific sizing options that accommodate their stature. Unfortunately, even if the colors had matched and the quality had been better, I doubt this suit would have fit him properly without additional alterations. Conclusion Overall, my experience with this 3-piece suit has been disappointing due to color discrepancies and poor quality construction. For anyone considering purchasing this item for someone tall or for themselves, I would recommend looking elsewhere unless you are prepared for potential issues with fit and appearance.

Excellent Affordable Suit for Special Occasions
Size: Large, Color: Black, Size: Large, Color: Black
Bought this for prom and was very happy with how it looked. The jacket is a nice medium weight and looked great on. We ordered a large, which was slightly big, but after having the suit tailored it fit perfectly. My son received many compliments and looked amazing.
