Nothing wrong with experimenting with a street car. We all like to go fast and air cleaner setups are the cheapest/easiest/fastest thing you can change at the track and perform actual back to back testing. As already mentioned there can be some significant gains with just air cleaners. Some are just absolutely horrendous.
