You're trying to solve a problem that doesn't exist.
It's supposed to be hot under the hood. Adding hood vents won't improve your performance or anything like that.
If you're doing it for looks, I totally understand. Just don't do it with the impression that you'll gain anything performance wise, because you won't. Cooler engine temperatures don't equate to anything.
Only putting this out there because some people seem to fall for the myth that making your engine run cooler will some sort of performance gain... which it will not.
I know there’s NO performance benefits to it engine wise, I just want to cool down the engine compartment a bit.
