Volant HV Cold Air Intake Replacement Filters with Donaldson PowerCore Filtration Technology

great product

The filter is an excellent product, but it did not fit as well as the original Power Core filter in my Volant filter box. Had to raise the box cover by 3/4 ". View more reviews...

Very happy with the replacement filter. Even more happy with my 63 series k&n CAI on my impala ss. I went from 18.5 average fuel economy to 20.4 average fuel economy. 21.0 on the highway.
