Holes in airbox

[Ameer Antar]

I don't understand why you would do this to your daily driver. Basically 
you're eliminating restriction of the air filter. This is just like what 
racers do in vintage racing when they put air horns on the carbs. There's 
no filter to decrease the airflow, making it easier for more air to get 
into the cylinders. That's fine if you're racing in known conditions and 
you rebuild the engine after a season anyway. But my car is a daily driver 
and it gets into all sorts of situations. Look at an old air filter and 
you'll the tons of fine dirt and dust it picks up. Why not just get a K&N 
or some other solution. A screened hole is still going to let in dust and 
sand, which is always around here in New England. Why not just take the 
filter out and leave off the cover? That'll give you better response, but 
how long will it last? Those not so little particles can get caught between 
cylinder rings and who knows what can happen. I just think there's a reason 
manuf.'s put use filters and don't put holes in air boxes...
