HPS Intake Dyno Results
http://www.youtube.com/watch?v=8sd-FkQwEkI
that's when the intake is on, but not on the dyno
this dyno was tested at the HPS facility using a Dynapack.. dyno numbers may be different, but the gain is there..

of course that may be different, but they also considered the map temperature and air temp.. fan blowing is the same as the car driving.. there's still an air vent that has air coming through.. obviously in order to keep the engine from overheating, hood has to be up..

On a nit-pick note, there is no "map temperature". The dyno was only adjusting for ambient temperature for the SAE correction. Real world results will be much worse than this. The common consensus is that all aftermarket (short ram / hot air) intakes actually reduce power for the ISX50.
i understand where you are going.. i understand that the stock box will give a better performance than the short ram intakes and i have nothing against what you say...
i'm only putting up the results of this intake through the dynapack..

You don't understand. The OEM intake is a cold air ntake that pulls air from in front of the radiator while the car is moving. All aftermarket intakes pull in air from inside the engine compartment, which is MUCH hotter with the hood closed since it has to pass throught the radiator.

You're losing maybe 3-5 hp, nothing anyone could possibly "notice" in casual driving. Doesn't make the loss not exist though.
Short rams can show gains on vehicles that otherwise have crappy/restrictive stock intakes... the ISx50 just isn't such a vehicle.

No company would discontinue a product that makes good profit. K&N doesn't produce intakes or filters because they improve performance. They produce them because people buy them.
