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.This Part Fits:

Perfect first shark book for littles
Format: Paperback
The book is super easy to read to my 4 year old son! He’s been really into sharks so I wanted something that was overpowered by facts on each page. This one is perfect! Each page has a different shark and the page do not have lengthy text but enough to still be educational. Keeps his attention and he’s able to learn a little bit about each shark. Perfect first shark book!

Great pictures and good information
Format: Paperback
Wonderful pictures allow my 3 yr old grandson to not only learn about many sharks , but good information as well. He can name the sharks , memorizing them perhaps, but yet has learned the distinct features of many from this book.

Surprisingly awesome
Format: Paperback
This book is awesome. I was pleasantly surprised at the detailed information inside considering its price.
My kids are 2 and 5 and love looking at the pictures while I read the information to them. It’s not so overboard that my it’s over my 5 year old’s head but detailed enough to supply him with new knowledge.
This is perfect to go along with our household shark obsession.
