I bought my car with an aem intake. The filter was bad so i put on an injen filter from my old lancer. Then everytime i shut my car off, it would rattle for a second. I tried switching to a z tube but that didnt fix it. My old car did the same thing with the injen filter so do you think that might be the problem? Should i go to say a pop charger? Why are the jwt pop chargers so commonly used? Thanks
