CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 1M/135i/335i/Z4 running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.This Part Fits:

toe strap is tewww tight
Size: 8, Color: Black
I love the look of these heels, they’re super classy, elegant, simple, and most importantly I chose these because of the small platform at the base of the heel for a less painful experience. The onlyyyyyy issue I have is that the toe strap is so close to the front and tight (as you can see)!! I got the correct size but wish I didn’t have to stretch them out (which is almost impossible because that leather is stiff). The shoe is not very bendable but I personally like it because the shoe is sturdy.

Poor Quality for the Cost !!! Dissatisfied
Disappointed Durability. I love these heels they are very comfortable looks good with just about any color outfit . However, my heart ripped in pieces after 3 months with limited wear they began to lift and fall apart . I’m very dissatisfied with the cost & poor quality slippers I received. I wish I could actually returned it but couldn’t due to the 30 days return policy.

Steve Madden must have
Size: 7.5, Color: Black
You can’t go wrong with any Steve Madden shoe to be honest. These are sexy yet sturdy. Nice thin versatile heel. Strap length is good for any size ankle really

Very Good Item
Size: 8, Color: Gold
I recently purchased these Amazon Essentials gold flip-flops at the start of spring, hoping to find an affordable sandal for everyday wear. After wearing them consistently for a few weeks I’ve gotten a good sense of their overall quality and comfort. One of the biggest positives is their style. The gold color is simple making them easy to dress up or down. I’ve been able to pair them with everything from athletic wear to casual dresses, which makes them a great staple piece. They’re also very lightweight, which is perfect for warmer weather or packing for trips. However, there are a few areas that could be improved. While they are comfortable at first, they don’t provide much arch support, which can make longer walks a bit uncomfortable. After wearing them for extended periods, I noticed some slight soreness in my feet. Softer, more flexible straps from the start would also improve comfort right out of the box. For shoppers, I would recommend these flip-flops if you’re looking for a stylish, budget friendly option for light use rather than something for long distance walking. Overall, I’m happy with this purchase. These flip-flops are a great option for casual wear and offer good value for the price, as long as you know their limitations.

They fit true to size and have excellent traction, making them feel very secure and slip-resistant.
Size: 9.5 Wide, Color: Black White Snake Print
I would buy these sandals in every color. The sole is very sturdy and supportive, not flimsy at all, which makes them super comfortable for all-day wear. The thong strap is soft and doesn’t rub or hurt between my toes like some sandals do. They fit true to size and have excellent traction, making them feel very secure and slip-resistant while walking. Overall, these are stylish, comfortable, and surprisingly well-made for everyday use.
