Hole saw will work best, you can also drill a small hole and enlarge it with a small drum sander on the end of a drill or air tool.

Cool thanks for the advice. Ill pick up a hole saw.
I have found that when using a hole saw on hoods and bodywork that I have better luck spinning the saw in reverse. It is less aggressive and will not grab and tear.
I like to go just smaller than finish size and then use a deburring tool to clean up the edges to come to the size I want.

Full vents in the rubber frame or just stick ons?
Full vents, use a hole saw in reverse.
If it's a stick on vent, mark it out and drill a series of small holes to provide some backing for the material.

I usually use a dremel mulit tool, takes concentration but no chance of ripping. plan where you put these though. you don't want them in a place they will start a crack when you hit some branches or roll it over
If it's for a large vent, I always had better luck with drilling several small holes to provide some rigidity to the vent. Most vents are pretty flimsy when snow or some other force is pushing against them. Nice to have a little backing material behind that vent for support. Oh, and as others have stated, run the hole saw in reverse. You can make a hell of a mess out of a panel/hood with a hole saw. Ask me how I know haha.....
