The mentioned induction gave an initial improvement of 12.8bhp (torque improved as well [for UKoldskool ]) before the ECU was able to adjust properly. The exhaust was fitted at a later time and gives about 21bhp as a single modification. Exhaust and induction enhance each others improvement. With a proper re-map (supplied by Chipped UK; wouldn't trust anyone else) the claimed figure was achieved enabling a proper driver to achieve a high 13 1/4mile time.

I believe that OEM air box in probably not the best performance item but concerning the Autodelta or force G/Asso carbon pipe, it's just a piece of carbon/kevlar replacing the resonator box, as it is still conected to the OEM airbox, I'm not sure of the gain, even with a sport filter inside the box.

BMC is certaintly different, as the K&N 57i.

On the picture of the GSR, I can't see how it's conected to the OEM airbox and MAF. Did it replaced it ?
