I know most people put them under hood... but I know a few people that put them in the car... My mechanic said, "due to the humidity (living in FL) you should put it inside... MSD says, "they're designed to live under the hood" (they may be biased, since they may want to charge to fix it later)...

So people, whadduya think?

I've never seen a problem with one mounted under the hood.
