One the people that have removed them and the affects or even why ford actually put this restrictor there in the first place..?? If anyone can shed some light on the subject with either facts of personal experience it would be much appreciation.. If ford put this in place purely to reduce induction noise I’m not worried about the noise as long as there is some kind in performance gain to be had and no damage at all to the car I’m happy to remove Cheers..

Just run the car on 95 octane or 98 octane fuel - that will boost torque and power. The air systems on these cars are very efficient. Link to comment Share on other sites More sharing options...

BRK Member 361 Member For: 12y 10m 5d Gender: Male Location: Perth Posted 07/08/13 06:38 AM Share Posted 07/08/13 06:38 AM Me too. A load of noise and some "whoopee" in the drivers seat means nothing. But, g5jett, its your car so you decide - but have think about this as a tested fact. BF series 2 XR6 turbo with light modifications dynoed with factory F6 air system made 240rwkw. The whole air box system was removed and a piece of pvc pipe connected to the crossover and ran out of the engine bay. Two more runs. Not ONE RWKW recorded on the dyno. The three graphs were identical. The stock BF F6 airbox does not look that special and mine sure does not have some sort of "cyclone blaster air turbulence ultra-cone" filter in it because at the power level and a bit above, what is there works really wellThe factory air systems are efficient. If you want to do something to your car that will guaranteed make power - get it retuned to run on 98 octane fuel. That will see it pick up both torque and power.Anyway - if all this helps you as a modifier, then the forum has succeeded. Its your car and your call.

A bit of dust won hurt it. Link to comment Share on other sites More sharing options...
