Genuine Hyundai Oil Filter, 26320-3C100, Case of 5

I bought a 10 pack of these a few years ago for my 2 Sonatas from another seller and never had a problem with them. I have used 2 out of the 5 from this seller DD Autoparts and both of my cars experienced knocking at startup. This is usually a complaint that comes with using cheap aftermarket filters and is the main reason I have been using OE for many years.I never had a problem until installing this new batch from DC autoparts. I bought 5 and used 2 on 2 different cars. Neither of them knocked before installing these filters. After installing, they both knocked on startup after sitting overnight or around 6 hours or more. I decided to install a Wix 57061 as I've always used Wix in all my other vehicles and the knocking went away after the initial startup and has never come back even sitting over a few days. I will be throwing my remaining 3 filters away I got from this batch and using Wix from now on. Don't know if these are counterfeit or just a bad batch, but I would never expect this from an OE filter.

The Oil filters shipped fast ... price is about half of what you would spend at the Hyundai parts counter.
