However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations.

Like the other cooling systems on the F8X, the factory auxiliary radiators do a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners have pushed the limits of their S55, CSF saw the need and demand. The F8X platform is also almost a decade old with the newest examples being at least 5 years old. Over time the original coolers end up with damaged or clogged fins that greatly reduce their cooling capacity.

CSF designed the coolers to be a true "Drop-in Fit" for easy installation. Each cooler mounts in the factory location and uses the OEM quick connections. The High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges, but prolong the heat soak threshold. There's nothing worse than having your track session cut short because you need to do a cooldown lap.

Compared to the OEM F8X coolers, the CSF units are a significant upgrade. CSF eliminated the OE plastic mounting pod by incorporating it into the modular design that fits both sides. This design improvement increases the size of both the core and tanks. The extra space taken from the mounting pod allowed for a ~7% increase in Core Size and an ~10% increase in Tank Volume. With a larger 2-row 42mm core, cooling efficiency and capacity are drastically increased. The high efficiency core using CSF's Exclusive B-Tube Technology maximizes airflow and heat dissipation. 100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and offers a stealthy look behind the grilles of your F8X. In addition, the CSF auxiliary radiators also feature integrated bolt on rock guards to keep the coolers safe. You've no doubt heard horror stories about OEM coolers getting punctured and spilling fluids all over the road or track. Now you can feel more confident that your cooling system is safer from road debris.

    Great item to make life more pleasant!
    Style: Contempo
    A tiny item that makes my life more lovely. No more yucky scrubber residue all over the counter edge, or soap leaking all over from a faulty handle. A sponge can be at hand and I can hang my cloth somewhere besides the top of the faucet. The suction cups stuck well now at first, and I can move it whenever I want. Not to big nor too small. Wire is firm and strong. Will edit if it doesn’t hold up but right now highly recommend! Edit to add: A bit disappointing that the suction cups are not reliable. Even after carefully cleaning the side of my deep sink with vinegar and washing the suction cups, they come loose about once a day. Giving them a hard push on seems to help, but not a cure. I revised the rating to average 3 stars. It really isn’t a problem in the sink.

    Stays put and does the job
    Style: Contempo
    I hate clutter. That includes my sink area. This holds my oxo scrubber and a sponge with ease. It also lets everything drain nice so there is no issue with slime or smell that other caddies have. Looks nice and amazingly the suction cups work. So far the finish is holding up and for what it is, it does its job. Looks nice.

    Oh how I love this little Gem
    Color: Silver
    I needed this badly as I often got irritated with the kids for putting the sponge back in the soap/scrubber dish and it was always full of water. I looked at options on the side of a sink but none were quite right for our set up...Then I saw this. What I love is it is not one more thing on the counter. It is below down in the sink. And yet, it is handy. Into it I have the essentials I use so many times a day right there handy and they drain on their own. This adhered well because I used rubbing alcohol to clean the area, then waited several hours before adhering set up to sink about 10 pm at night. Letting it set over night and in the morning I remembered the tip another reviewer wrote to push the tray down STRONG until it CLICKS into the holders. Then it was completely sturdy and firm and I've used it long enough to know I'm very happy for this small perfectly practical way to hold my sink tools. So glad I chose this much less expensive simple one.

    Highly Recommend
    Color: Silver
    Love this holder of all the things! We purchased this 4 years ago and it has work great, rust-free, until my husband piled two pots on it and it broke last night. I am immediately purchasing another one. It is very easy to install and stays put, no movement at all.
