Is it really worth putting a Cold Air Intake on 370z and what HP gains

I 'm using the motor trend nismo to the base model comparisin , to show what little effect a marginal HP increase, in this case none.

Dyno runs are one thing to show performance and I would agree that a 50-100 hp increase would definitly be felt by the driver, but with the marginal 5-10HP from an intake kit, it may not even provide any better numbers than stock if it were tested on the street for 0-60 , 1/4 mile and top end. Test results may even prove worse.

Another thing to point out is that once a modification has been made to the exhaust or intake, the engine requires a new engine map to installed by either a laptop with a proven map for your specific geographical location or a manually adjusted map, calibrated with a dyno and a laptop. In order to take full advantage of the mods.

I know the ECM will relearn itself, as you drive it , but it will not optimize for the best peformance possible, when compared to a dyno/mapping adjustment.
