The "overflow" tank on your NC is actually pressurized and part of the cooling system. The oldest ones are now over a decade old, which is asking a lot for a plastic box that's a critical part and exposed to high heat levels. We've seen a few damaged engines from cracks in the stock tank, leading to a loss of pressure in the system and overheating. This aluminum part will solve that problem and give your NC the protection it needs.
Plus it looks awesome.
Bolt-in replacement for stock. Includes a sight tube so you can check coolant level. Fits all NC models. Exclusive to FM!
