I've got an open-style K&N filter underhood, it's right next to the engine, so it sucks pretty hot air. I will be installing a hood vent near the filter. My question is where to cut the hole. Directly above the filter, in front of the filter, behind the filter or anywhere else? I also have York right there, so it would help cool it down too. I am mostly concerned with air flow during slow speed crawling. Would an aux. fan in the vent be a good idea to push the hot air out?
