Review on Mishimoto MMAI MUS4 15P Ecoboost Performance Polished by Rick Kreutzer

Revainrating 1 out of 5

Just say no! best parts

Very cheap junk. There is no installation guide with video link which is terrible. The dose of the filter does not fit in the hole, it must be broken in place. The tube is very thin, aluminum. The silicone hose has parts of bad molding full of air bubbles. The hole for the air temperature sensor is very sloppy and air can get in.

Pros
  • 155% more filter area, works to 2000 cfm
Cons
  • 0
