How much was that Jim Wolf Pop Charger?justkickin said:I have the Jim Wolf Pop Charger (basically WAI) and like it. Works well. Doesn't make much noise at low RPM, but get on it and listen to it howl going over 4000RPM. I went this way for climate reasons (and based on Andy's recommendation at HPAuto), you don't get sub 30 Celsius weather in Van so the CAI may work for you. However, it can get chilly out there, and too much cold air is not a good thing.
