They should be the same filter. Wix makes Napa & Carquest filters & the numbers are the same except the first number. It may have been boxed wrong. The original equipment fiter is AC. It uses a 5/8 wrench on the cover bolt. The aftermarket filter was Fram. It uses a 7/8 wrench on the cover bolt. Sometimes this causes confusion at the parts counter as they take different cartridges.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
