Good lead weights

This k%26n filter fit perfectly in my 2018 GMC Sierra SLT with a 5.3 L V8 engine. This filter is a great value and according to the directions you do not need to do anything to it for up to 10 years but we will see sure I will be cleaning it and re-oiling it in about two years as I have done in the past in other vehicles. All in all great filter great price. I'm really happy that Walmart carries them.

Way Better Than Stock

This is an incredible option for someone who wants the ability to clean and reuse the filter vs having to put a new disposal filter! Talk about a fantastic to limit maintenance cost and have a product that preforms better than stock paper filter!
