Review on AEM AEM 21 819 Cold Intake System by Justin Hollins

Installed on 2018 3.0T. They only fit passenger B to snap him back into the maf hose. First you need to remove the strut and then route the hose over the inlet as shown in the picture and you need to get the clip in place to allow it to snap into place. One person held down the case while I ran my hands over every area I could reach to close it. Squeeze the MAF hose until it snaps into place. Be careful of how the filters are seated as they need to be seated to clean things. I used a precision knife to cut the inside of the hoses they sent so the air filters went all the way down. Overall it's a good system and I haven't had any error codes and haven't had to remove the battery clips or anything.
