Aftermarket Air Filters? What did you choose?

Hey fellow Bronco enthusiasts! Just wondering how many of you have went with an aftermarket air filter and if so what filter did you go with? I just ordered the Whipple filter for mine. I liked the fact it had the velocity stack on it, for more airflow and surface area. The other filters I have looked at K&N, Afe, BMC did not have the velocity stack with the extra surface area the tops are closed off. The only other filters I saw with the velocity stack was the S&B but they were out of stock. So have you upgraded you air filter or stuck with the paper oem?
