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.

Sway Alert!! This is a beautiful suite!
Color: Beige, Size: 5, Color: Beige, Size: 5
This suit fit great my son loved it. The quality is good. My son is five about 40 inches tall around 40 pounds. He’s very slim but the length was great. The suit jacket fit well. The pants waist were a little big, but the adjustable strap helped with that, but the fit overall was great . I would purchase a suit again in a different color.

Great Looking Suit with Lightweight Material
Color: Light Grey, Size: 7
I got this for a beach wedding and it worked out really well. It looked nice without feeling too formal, which was perfect for the setting. The material is linen and it feels lightweight and breathable. It kept my kid comfortable in the heat and didn’t feel stiff or heavy like some dress suits do. The appearance is sharp. The double breasted style makes it look more dressed up, but the linen material keeps it relaxed and appropriate for outdoor events. The fit was true to size. It sat well without looking baggy or tight, and everything stayed in place throughout the event. Quality feels good for the price. The fabric and stitching don’t feel cheap, and it held up well after a full day of wear. Suitability is great for things like weddings, parties, or photos. It works especially well for warmer weather because of the material. For value, I think it’s worth it. You’re getting a nice looking suit with comfortable material that actually works in real situations. Overall, great fit, breathable material, and a clean look that works really well for events.

Very nice linen suit for boys. Well worth the piece
Color: Beige, Size: 12
This JPF Double Breasted Linen Suit for Boys is the cutest thing I've ever seen! I got itt for my 8 year old and he loves it! He tried it on at soon as we received it and wore it all evening. Lol. He looks so grown up! He's about 4'3", about 75lbs. I ordered a size 12 and it fits him the way I'd expect it to. A bit big but he has room to grow into it. It is a 2 piece suit, with pants and blazer only. It's a summer suit, it's meant to have a more laid back, casual style. It is so nice! The style and color are identical to the photo. I got the beige color, that's the color my kid picked. I do worry a bit about staining, considering an 8 year old boy will be wearing it, but hopefully any stains will be easy to remove. The quality is excellent and the price isn't bad either. I highly recommend this suit

A charming summer suit
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This suit fit true to size. The light grey wasn’t exactly the same as advertised (see photo), but I still really like it. My son felt snazzy in this suit, and he said it was comfortable to wear.

Nice suit for the price!
Color: Light Grey, Size: 12, Color: Light Grey, Size: 12
This really is a very nice boys suit, especially for the price they are asking. My kids don't wear suits too often, maybe once or twice a year for special occasions so I don't need really expensive suits for them. The material is actually really nice on this. The color looks great and the pieces are sewn nicely. The adjustable waist band is really nice on the pants because my kids are on the slimmer side and this helps with fitting. You can also wear a belt with these if needed. I washed on delicate cycle and dried on delicate cycle a little, then finished by air drying. They washed and dried very nicely with minimal wrinkling. The front pockets are real and useable on these, which isn't always the case with boys suits. Overall would 100% recommend
