I don't post much but I can give you some information on how to save big on FILTERS in general. Twice a year every NAPA store is eligible to have a filter sale on the NAPA gold filters. My local store just had theirs. The filters eligible are the GOLD series filters. I am always buying filters for the endless amount of cars, trucks, and equipment I own, not to mention batteries! I currently buy the two fuel filters for $68.00 during the sale. I have a spreadsheet of every oil, fuel, hydr, and air filter I will ever use and I keep them in stock and always rebuy/restock when the sale comes around. Another tidbit of information... No two NAPA stores have a filter sale at the same time. So, that means somewhere this week a NAPA store is holding a filter sale.
Several debates exist in my post.....
1) Yes, these are aftermarket and not oem filters.
2) Do they meet the manufacturer requirements?
3) What protection do I have?
Let me kind of sum up those questions. In my experience, I have found NAPA gold filters to be a great filter and in most cases meet or exceed the manufacturers requirements. NAPA (Genuine Parts Co.) is a huge corporation that has an outstanding reputation and will most certainly stand behind their product and any defects it has or may cause. BTW most of the NAPA gold filters are WIX filters FYI. Next, there is this law that exists called Magnuson–Moss Warranty Act. Check it out sometime. In general terms it is made clear that the manufacturer can not deny you warranty on your product if you use an aftermarket filter. You can pick up one of these cards at your local NAPA store that breaks it down a little further.
I am not endorsing NAPA by any means. In fact, I give my spreadsheet to all of my competing parts stores twice a year when I source my filters and tell them I have 10% loyalty factor. Also, from experience with CAT, I have had to deal with the Magnuson–Moss Warranty Act. CAT is a real pain to deal with when it comes to filters and their warranty! At the end of the day there are only a handful of companies that make filters chances are yours might be one in a different box!
The “NP” suffix in the filter number indicates that a new multilayered nanofiber filter media is used. The Prefix “nano” means billionth, so by definition, a nanofiber is defined as one that is less than 100 nanometers in diameter. To put this into perspective, a human hair measures approximately 50 Microns in diameter. One of those microns would be 100 times larger than a nanofiber. The NAPA reps will also talk with you so ask your store to talk to a local NAPA Filters District Manager.
Another FYI, the Cartridge fuel filter they offer is rated at a nominal micron rating of 2!
