Did some more reading...feel like a noob

From what I read about installing performance air filters, I would need to get the engine more in tune since I have placed a filter that would increase the flow or air inside the engine. (I feel like my dad when I show him how to do something on a PC!) So for my mini road trip I am going to get the basic STP filter until I get a flow kit. Any recommends?

I just replaced the air filter on our TB and cut part of the front box out to allow more of the cool air to get to the filter that comes through the front tube and I took that flat piece of plastic that is snapped into the grill that kind of directs the air into the radiator off so it will flow back into the tube for the air box, interested to see if it helps any.

was that worth the work compared to just leaving the stock little tube alone?
