I've had stock, AEM short ram, and AEM cold air.

Car came with stock. plastic intake arm was ripped so I got a used AEM SRI for $50. No real power gains. The noise however.....lol. SRI's are loud. At full throttle at high RPMs it just resonates through the whole car. Recently traded my SRI for an AEM cold air. Did mostly because I will be tracking my car in the near future, and wanted something I could run ducting from my bumper grill to the filter easily. Also no real power increase. But I did notice in warmer weather the intake will not get heatsoaked as easily, plus its pulling colder air. Maybe a 1-2hp gain, but throttle response is a bit better. And its quieter than the SRI, but still loud enough to put a smile on your face.



Here's my AEM intake with the optional bypass valve so I never have to worry about sucking up water.
