rad overflow tank

[C2]

I had to remove the rad overflow bag to install new K&N air filter and headers. I need to find a replacement and was wondering what other guys have done. Is there a particular size requirement? I have seen some stainless and ploished aluminum tanks that look good.
PS I am no expert but the new air filter and SoCal headers seem to make a big difference in Hp.

If u go to use one of the tanks dont forget to put a sight glass in....you can do this with cleer plastic hose.I have seen this done in the miata and rx-8 comunitise. I think it would look good and i even thought of it the first time i looked in to the fiat moter bay. Gool luck and post pix for us.



thanks
