Wow guys, I must say that by cutting EVERYTHING ouy underneath the air filters, my buddies IROC gained tons of throttle response and some really good power, I recommend this to everybody.

i measures the sq area of the box, then the sq area of the plastic obstruction, and by cutting it out, it gives your 32 percent better airflow. Thats about 60 cfm.
I also noticed a big difference in throttle response.
