My truck is stock, and for the most part MAY stay that way. I need to replace the air filter. Will most likely choose the the AFE setup and do that b-4 winter, but until then..what would be a good filter to use in the stock box? or are there any? Thanks for the advice. Ken

 

A good name brand from your local parts house if you are leaving it stock until your AFE goes in. A good free flowing air and exhaust will do wonders for your truck.Goodluck,,Rick

 

A good free and easy first upgrade to increase airflow is to remove the restrictive"snorkel" that goes between the airbox and firewall.
