Good genuine factory ac delco filter.
Exact oem replacement. Fits 2024 terrain, easy to change using a nut driver @ 13,000 miles. Old filter had some dirt on it but wasn't too bad. Good price compared to others although I think it should be about $15. A clean filter is important on turbos. You need good air flow. I chose oem because of warranty, reliability and to keep it factory as the manufacturer intended. Mine says made in Mexico.

Perfect fit for 2020 Chevy Equinox - Easy project for anyone with a screwdriver
Changing car filters is one of the simplest money-saving maintenance items you can do for your car. I currently drive a 2020 Chevy Equinox LT and was quoted almost $175 to change the cabin and engine air filters by the dealer during routine maintenance. I politely declined and bought this engine air filter while they finished up.. Armed with just a screwdriver and 10 minutes of free time I removed the old filter, cleaned up some accumulated leaves and debris and then replaced it with a new one. It's just that easy! The new filter is a perfect OEM fit for my car. It's indistinguishable from the one included by GM when I first purchased the car. Pro-tip for Equinox owners: you don't need to remove the screws all the way. You can unscrew them halfway from the bottom portion and they will securely stay attached to the lid as you make the swap.

Save yourself over $100 and replace this OEM filter at a much reduced price.
Every chance I get, I much rather go with OEM parts. The price of this item is excellent and since is OEM it can be trusted. My wife was told by the dealership that she needed to replace the engine air filter, and it would be over $100. She is smart enough to say no and that her husband would take care of it. Well, for $26 the filter was replaced in 5 minutes, and we save almost $100. No need to so into the actual components of this filter since it is genuine GM and if the manufacturer installed it in the vehicle it should be fine. It is just a matter of paying an additional $100 plus dollars for a five-minute job that anyone with just a screwdriver can do.
