Review on ACDelco A975C Professional Air Filter by Mikey Jackson

My 2017 QX60 lost 4mpg after installing this filter. After installation I reset my MPG meter and drove about 2,000 miles to make sure it wasn't a bug. After pulling out that Chinese trash filter and installing a $9 premium filter from a local parts store, my MPG immediately jumped 5mpg, 1mpg above average before I installed that one. my new filter, so maybe it didn't fit well? However, do not buy this filter if you have a QX60 or JX35. Purolator or CARQUEST Premium work much better on the QX60 in my experience.
