Anyone know the part # of the 01 Z06 mass air meter-my dealer says that it shows the 02 and the 01's to be the same. I need the screen-maybe I should ask for one from a 6 litre pickup-would it be calibrated the same? The part# they told me was 25-318411.

screen

Since the install of donaldson my LT fuel trims went way up to 15-19% and eventually they through a lean code. Apparently there is too much turbulance at the mouth of the meter and screen should straighten it out. Apparantely its just the design of the filter.

MAF

The number is correct, 2531-8411, it is the only one listed for the 2001 and 2002 Z06. It has the screen. I would like to know the number of the one without the screen. It has an air foil in the middle, unlike the one above if you were to take the screen out. Price $126.00

Sorry but !!!

The only maf listed is for both 2001 and 2002 and it has a screen.
The screenless mafs must be avaiable because Halltech is selling them, but Chevy has only 1 number for both.
