Filter needed a wash, and it needs to dry before oiling. So a little airflow from an exhaust fan, little heat from an AC exhaust.
And in less than an hour, a dry filter. Way better than just letting it sit for a day or two, especially in humid places.
Personally I don’t like them. A lot of people like them though, They’re marketed to give you more horsepower/ mileage but actual testing suggests otherwise. They may be useful if your engine is highly modified but they also let more dirt through, especially if you don’t oil them properly. https://www.nicoclub.com/archives/kn-vs-oem-filter.html
Excellent analysis, thank you!
