I don't have one yet but all I can recommend is that it is a C02 Extinguisher instead of one of the more common extinguishers that shoot white powder...

Allegedly if you have a fire under the hood and use the white chemical type you'll need an engine rebuild (according to 1958GMCNut) wink

I hope that helps...
