Well this filter should be familiar to some of us. It is the exact same oil filter that was selling in Autozone as the STP XL. Exact same specs... 99% @ 20 microns. Built like a tank. Premium Guard is the seller of this filter which is made in South Korea.
But this filter was only $5.39 an everyday price at Federated Auto. It was $8.69 at Autozone. So, for $5.39 everyday price is not all too shabby.
