The replacement was straight forward. No problems encountered. I did however install a pre-filter on the powercore since it cannot be cleaned. After about 4 days.....the mileage began to climb. I now get about 3 MPG MORE than with a standard Volant filter. The Hemi engine breathes better and has more power which can be really felt. I will get a replacement in another 100,000 miles.
