stock compared to monsterflow and different resonator, the average difference was +6 ft-lbs/+3 HP. peak was +9/+4.5, respectively. not bad.. but probably not noticeable either. it's worth noting that gains were across the board.



Most dyno's are done with a fan and with the hood OPEN. This means that there is no trapped hot air as hot air always rises. The open filter will always have an advantage in this test but real world road testing will be a little different.
