That doesn't apply to me to much
But leave them in. You'll probaly end up with dirt and dust in places you won't want it. If you really wanna vent the engine bay better, my guess would be just get a vented hood or something like that. I've also seen some track cars take dryer tubing, run the tubing from the holes in the front bumper and run them to someplace back near the motor. Usually 4th gens seem ok about air moving though the engine bay though.
