I got one of those oil filler filter breather caps and was wondering if this was a good idea. I was thinking that trash/tiny particles could possible make its way in. like if you are behind a dump truck or a car in front of you going through a dusty road. That trash could get into the valve cover and dirty things up.

Am I over reacting or is thia a ligit concern I have.

Also, my car is completely stock and my purpose for getting it was just to help the car breath better.

if you have EFI, i wouldn't use the breather cap. unless the whole pcv system is altered it will only create a vacuum leak by letting unmetered air in/out of your motor.
