I purchased a new 2025 Chevy suburban LT last August with the Duramax diesel engine and everyone lines it too much, already have 22,000 miles in it. So I am very careful with the Duramax and I add additives and take good care of it. The book says to change the internal cabin filter every 15,000 miles, I think it said. And I live on a farm, where I gave to drive about 3 miles on very dusty gravel roads to get to highway pavement. The reviews on this filter were pretty good and the price was reasonable. So I ordered one. Wish Chevy would make it just a little easier to install, but am happy they now have cabin filters as it really cuts down on inside dust build up.
