None really! The screen and divider are there to correct the air flow ( Straighten) after the stock air box. The stock air box setup creates a voilant turbulance, and if left the way it is, the motor couldnt get all the air it needed quick enough. The advantage of removing the screen and center bar ( In Theory) with and aftermarket intake, is too make it easier for the motor to get air it needs, hence more. The stock MAF and TBI unit are sized almost exact, and the TBI units determines the amount of air that can get in so removing all this doesnt really do alot more than make the air available. I will tell you all this, myself and 2 others persons from different boards have had this dynoed. Taking the screen and bar of lead to a loss of horsepower of 5-7. And when the grant unit was tried, 7-12 horsepower lost. Part of this is due to area, with the area size being increased the air movement slowed down enough that tha MAF didnt cool as far leading to a bad reading of air density and amout which also lead to a loss 1 degree of timing and fuel addage due to this misread.Danthemanxx said:whats the advantage of removing the screen??
