Per my invoice from TireRack and at AEM's site at one point.
hp = 7.9 gain at 6100rpm
trq = 9.5 gain at 4100rpm
I've owned all three of AEM's intake systems and I can definately say this one pulls like a mother - like none other. Above 4000rpm she really does pull. I had the OEM box on the car, no resonator, with a K&N filter prior to this -- and it clearly pulls much harder.
The numbers from AEM may infact be true. Remember these are peak gains, the power band is actually a bit less under the curve. BUt almost 10 ft-lbs. is freaken huge that low in the power band.
