Sold Individually – all applications require 2 auxiliary radiators

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.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

Very durable!
Color: Blue T-Bone, Size: 1 Count
Great product! Dogs love it and very durable. I had been buying the nylon bones in pack of 3, but my 2 dogs would chew them up in no time, and I was buying the aggressive chewer bones. Bought 2 of these, dogs loved it, so I bought another one. Have had these for about 2- 2 1/2 months and still holding up just fine. And the price is great! Would definitely recommend!

Great for chewing but very sharp and mangled in a few days
Color: Blue Gator, Size: 1 Count, Color: Blue Gator, Size: 1 Count
I thought this was a fantastic idea having baking soda added for fresh clean teeth while enjoying a new toy. I wanted to review 2 main things about this. First, if my dog enjoyed this toy. That answer would be yes absolutely! She is chewing it as I’m writing this right now. She can spend a good amount of time chewing away on this and it keeps her busy without having to use a rawhide treat which we only try to use if we re going to be gone for longer then 4 hours. The kids love playing fetch with her and she stays engaged the whole time. It is very heavy and when being thrown can become a weapon so I always supervise! Last, the durability of the toy. So it is durable but not completely. As you can see the toy got very sharp where she has been chewing it and I’ve even noticed a little blood on it which means it’s cutting her gums. It wasn’t a large enough amount for me to take it away. It is still almost the exact same size but maybe after a month I will re edit this for more accurate on durability since it’s only been about a week that she has gotten it. Overall, I would recommend this toy it’s a great price and keeps her attention a lot more then other toys I spent twice the amount of money on!
