Quote: The big retailers, Advance, Autozone, etc., tend to buy their products based on price. If it's cheap, they buy it. NAPA on the other hand, tends to buy product that meets and often exceeds OE specs. NAPA also checks what they buy to make sure it meets their specifications. The retailers usually do not.
If that's true, then are WIX filters bought at the big retailers different than the ones from the NAPA dealers?
