The cross referencing is NORMAL in most industries, albeit in oil filters also. It is very useful and a time saving procedure.
NO! They are NOT the same filter.
Fram has been vilified, (you can search,goggle for all the "bad news") but I would have no issues running them. Are there "better/worse" products? Absolutely !! I have in the past and actually still do run the Fram PH8A with 15,000 miles OCI's in the past and currently 15,000 to 20,000 OCI's. I have been doing this app 673,000 miles. (45-47 filters)
In addition, FRAM is the provider for the oem Honda oil filters (2004 MY anyway) . It goes without saying they are made to Honda's (unknown to most consumers) specifications. OEM Honda filters do cost more. Even on this august board, you'd be hard press to differentiate a statistically significant difference as measured in UOA's (Fram aftermarket, OEM Honda (made by Fram)cost more cost less, control, etc.,etc., in what ever test protocol you wish to use.
I have bought the FRAM brand for the Honda Civic, but it had more to do with the black grippy portion of the filter. (stupid I know, oem Honda filters do NOT have the black grippy portion on the outside of the filter) It does make changing the oil filter a snap.
However SuperTech (ST crossed referenced/correct) filters are far cheaper. They are (STILL) made by "Champion Labs." Again I have NO issues using them. In fact am currently on the early legs of the ST filter on the Honda Civic.
