Hey all, just curious to know what the screen in my intake system is for. There is a screen at the point where the filter hose meets the intake/TB system. What the heck is this screen for?
The honey comb is infront of the MAF because the Mass airflow is mostlikely measured by a hot wire aninometer. The need to measure air speed through the device, since they know the diamter of the device that gives you flow rate of the air and using the average density of air at that temperature (what the IAT is for) they know the mass of the air comming in.airbalancer said:If the sccreen is for straighting airflow then it should stay in as the senor may get a false reading
In the hvac industry turning vanes are used all the time to reduce trubance in the duct work and the less trubance the great the airflow
If then screen is clean it should not reduce airflow and the engine is design for the screen so you are chaning the specs if you take it out

This is my take on it... The screen protects and it also smooths airflow so the sensor is more accurate.. So that being said, IF YOU ARE INSTALLING A K&N FILTER or a new INTAKE system , knock the screen out! It does restrict some airflow. The K&N filter is DESIGNED to smooth the air flow so the screen wouldn't be necessary any more,......"
Just wanted to point out that the MAF installs AHEAD of the K&N ducting so it would recieve no direct benefit from the K&N's airflow characteristics. The K&N's smoothing effect will mainly benefit airflow through the throttle body.The screen is directly ahead of the MAF so it DOES have a direct effect on the aitflow across the sensor. The question is, does it REALLY matter?
