i just got a KN 57-3026 air intake system for my 1995 gmc sierra and i got everything installed correctly and it‘s working good so far but i still have a little mini looking vent filter thing with a clamp and it doesn‘t say in the instructions of where to put it?
yeap just the pcv hose go to autozone they have mini filters you can put on it if your intake dont have a nipple to hook it up
probably a crankcase vent,goes on the valve cover
it might be for the valve cover as the breather, i have a 98 Chevy Silverado with a 5.7L and the KN air intake but the stock intake just had a rubber hose going from the intake tube to the valve cover so the KN tube had the same hole to plug the rubber hose to, it works the same way just not with a small filter directly on the valve cover, just takes a little of the air from the intake tube for the engine and directs to the valve cover if you have the hose like on mine that goes from the KN intake tube into the valve cover then the little filter you can throw away or keep
