+1 on this. The airflow difference between aftermarket and stock is really isn't required until after you have so much horsepower going over stock. Better to protect your motor catching more particles then minor airflow increase that your motor doesn't need.
Picking air filter is like picking oil also in most eyes. So opinions will vary.
Want more air,do the air box mod. best results if you get a "Custom" tune after wards. works best with full aftermarket exhaust also. As goal is to get the flow going into the motor and out of the motor as fast as possible.
