ACDelco GM Original Equipment A3244C Air Filter

Same as original

Reading the fitment description and reviews on this filter were a tad confusing. We have a 2021 GMC Sierra Denali with the 3.0l Diesel engine. I am happy to say that despite some reviews, this is the exact fit filter for this engine. Our local dealer wanted to charge us almost 4 times the cost of this filter to have it replaced by them. Granted there are a few screws to remove and I did remove the air tube to make things easier but we saved a pile of money doing it ourselves. As you can see from the images, the original filter is after 3 years of normal driving in Northern Ontario. It's not bad at all. That foam pre-filter takes the brunt of the dirt. Overall, it's an easy job to do and doing it yourself saves a ton of money. Not to mention it gives you a chance to clean things better than a dealer would.

Fit like a glove!!
