Can’t go wrong with KN
Been using for years in all my vehicles. One time pricey but then years of trouble free performance enhancing filtration for your engine. Five minutes to install on 24’ Honda Pilot.

Worth it!
Perfect fit for my 23 MDX, easy to install and great value for money. Dealership quoted me a ridiculous amount to replace the air filter. I would recommend everyone to DIY. Bought it together with the cabin air filter. Will definitely keep an eye on longevity. These are washable so probably wont need to buy for at least a couple years.
