If you keep your vehicles a few years this will save money
I have been using K&N for 50 years very good quality over OEM filters and it gives your engine better breathing. Saves money over the long run.

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.
