OEM quality and perfect fit with no leaks
Size: 1 Count
This is the real deal for anyone wanting to stick with OEM parts for their Chrysler or Dodge vehicle. The filter arrived sealed and well-packaged, and installation was quick with no surprises. This fits my 2016 Chrysler 300 sedan. It fits perfectly and performs just like the one from the dealership but without the inflated price. There were no leaks, and oil pressure stayed consistent post-change. If you're doing your own oil changes, it’s worth sticking with a filter that’s built specifically for your engine - this one does the job right. Pros: True OEM fit and function Well-sealed and clean install Performs reliably Tip: Pre-fill the filter with oil before installation to reduce dry start wear and improve circulation right away.

Mopar Quality
Size: 1 Count
I regularly buy Mopar filters for my vehicles and have never had a problem with them. These are great filters at a good price and of course it is very convenient buying on Amazon.
