It is, and it does, and that's why it's there--in fact in Greg Banish's book Engine Management and Advanced Tuning, on page 28, an assembled Mustang MAF, screen, and airbox back cover are used to illustrate same.



I would strongly recommend that you buy and read Greg's book, it is pretty much the definitive work for modern engine tuning.

when i do buy a cold air intake do i remove the screen?

I have a 96 GT and I bought the whole K&N intake and took the screen out and she runs fine. I have never had a problem. so maybe the only reason people have problems with take the screen out is when you still use the stock intake...

First of all, assuming you have the OEM intake, you currently have a CAI--and a pretty good one at that. Most aftermarket CAIs are 99.44% eyewash, the exception being predominately the JLT offerings which like the OEM intake are engineered as more than just a piece of tubing.

As to the screen, removing it will not make any measurable difference in power and may affect drivability--take it out and see what happens, it's not a big deal to put it back in.

thanks cliffyk for the info.

im sure it varies on which intake you buy. the K&N intake tells you to take out the screen. and leave it out so idk.

also if you are going to get a new intake i would go with the ram air design keeping your filter out of your fender. after talking to a lot of people about which was better, they all agreed on the ram air intake because by putting the filter in the fender like most cai its more susceptible to moisture which as im sure you know is bad for your engine.
