Question 1 depends on whose propaganda you believe, my personal opinion is they are a waste of cash, you need to spend a lot of cash to get more power from a normally aspirated engine. Insurance possibly yes.

I would agree.

I recall reading a report that said they do let more air through than a standard manufacturer's filter because they've got bigger holes.

That means they also let more dirt through.

They can be an advantage if you've made other modifications that can benefit from fitting them.

Take your air filter out and see if it makes any difference.

The only difference you will find over a standard air filter is in your wallet.
