I want to purchase the NAPA BHAF; however when I checked with my local NAPA store, they priced the filter at $55. 89. I did a search on this site and a lot of you guys are paying $32+ for this filter. What gives? Has NAPA raised the price since the demand for these filters has grown, substantially I'm sure. This store does not stock the filter but can get it from their warehouse in one day. Also, I did call Cummins Southern Plaines here in Fort Worth and they sell the Fleetguard AH19037 ( BHAF) for $36. 58 so I guess I will have them order the Fleetguard filter for me.
