Intake Charge Kits... Yes or no?
I recently ordered an APE filter for my M3... which, as most people on here say is the exact same thing as the Macht Schnell filter. I've heard of some generous power gains to be had from adding a charge kit to the filter.
Do the charge kits really do a whole lot for gains? If so, who would you recommend? No, I don't care if it is carbon fiber since its under the hood and me nor anyone else ever sees it. I just want something that is quality and fuctional.
