I have read an article about taking off the stock air filter system and replacing it with a K&N filter. Here is the article http://home.tampabay.rr.com/redroby/3liter/ at the end of the section titled
installing a K&N Filter it instructs you to replace the computer without the cover on for extra air flow. Will this be ok or should it still have an external fan on it??
