Nice filter and good price.

Perfect fit
This filter is awesome, exceeds the oem filter from dodge. Has a great red color (obviously has nothing to do with performance but from an esthetic point of few it’s a nice touch I dig it. By way of performance it looks to be just as good if not better. Time will tell! Filter is a perfect fit for my Ram 1500 (2021) Laramie 5.7l engine. If you’re looking for a good filter this is a perfect replacement and very reasonably priced. Thanks!
