I have been saying this for two years!! It's mind boggling to me that everyone just assumes the RF is the best route possible when the only metric I can find is the noise it makes that is better than the stock airbox. Our dyno results with Project Shocker made 697rwhp and 715lb/ft with the stock airbox and filter on an e30% blend.
Add road course track use to the mix and now I have 800-1000º+ brake temps plus tire and road heat going into the airbox from below with all the debris it can carry. At the last event, my tire threw a rock so hard it went through the fender liner and into the headlamp housing, now causing it to catch debris and water vapor.
