I reluctantly gave the ZZP 3" intake 3 stars. Once installed it sounded great, now I can hear the supercharger under boost.
However there were a few problems with the install and fitment.
1. The hole for the MAF sensor was too small. To make the sensor fit we had to file out the hole for almost a half hour, not cool! Once we did get it to fit, it does not fit flush with the mounting plate, oh well.
2. I found a small loose piece of metal left over from manufacture on the inside of one of the tubes. It was an 1/8 in round piece that I could easily remove with my fingernail. Glad I caught it before I started the engine.
3. After the first time it rained it started bucking and stumbling under boost. Of course the filter got wet, which caused a MAF engine trouble code. If you run this filter on an Ion Redline you must also install a waterproof membrane or forget about driving in the rain.
