Review on 🔒 Wix 33960XE Fuel Filter: Ultimate Performance and Durability for Optimal Engine Efficiency by Scott Clayton

Excellent filter. 7 microns! However, when I changed the fuel filter and started my 2016 Duramax, the check engine light came on. This is common from what I've read on the Duramax forum when using the Wix 33960XE. Don't be alarmed, this is NOT a #8 glow plug, sensor, etc. It was getting late so I decided to wait until morning to take it to Arizona or a dealer to install it on my computer . The next morning I started the car and the check engine light went out. It is a personal decision which filter to buy. Either AC Delco or Wix. Both are excellent choices. I'll stick with AC Delco because I don't need the headache trying to find the gremlin that caused the check engine light to come on. Have fun and safe driving :)
