ok, ive heard and read alot about people removing the MAF screens in there cars, but since im new, i do not yet know what it is for. will it hurt my cars performance since it is a stock 2003 SSEI with 19000 miles , or help it. And how would i go bout doing this. Thanx

the screen is used to straighten out the ariflow over the MAF sensor or it can get an accurate reading. only remove the MAF screen if you have a aftermarket intake on the car (rice pipe or the like), or a gutted airbox. some people believe that the MAF slows down the air, and others dont. there have been no factual proof that the MAF improves or hurts performance. some have experienced a rough idle upon removal

in summary, there is no proven gains with the MAF out or in

Couple of disclaimers first...

My engine is NA (No supercharger) and I am not sure of the differences between the 98 and your intakes, but....

I have had my MAF screen out almost since I bought the car, and I have had no problems what so ever. And it adds a bit of Seat of the Pants feel-able power.

Others, tho, don't like the idea. The nice part is, if you take it out carefully, you can always put it back.

thanx alot , i might remove it after i get my CAI and smaller supercharger pulley

It'* a lil louder sounding without it, and a smooth pipe will negate the use of the screen.

I had issues taking mine out, mostly with rough idle. I replaced it and all is well. Your mileage may vary.

No problems here either

When I removed it form my 1996 oldsmobile with a n/a Series 2 I had no problem. I didn't even put it back in when I sold the car.

For my 1990 park avenue when I removed it I had a ROUGH idle and I felt no performance gain so I put it back in.

def. hurts idle with no performance. leave it in

How long did you leave it out for? Mine idled rough for a while too, but the computer seemed to trim it out in a few hours of driving.
