I am trying to find the O.D. of the SLP MAF, I have tried for about 30 minutes, with no luck. Also, are all 90mm TB's the same O.D. (~4") as the stock TB?
If someone could measure them for me or post up if you already know, I would greatly appreciate it.
I am trying to get hose and fittings bought to do a custom air filter setup and need to make sure I get the right size.

Thanks, James.

I'm 99% sure that the SLP is an 85mm ACDelco with a resistor soldered in. Here's the measurements from the 2002 z06 MAF I have here (85mm ACDelco). Part# 25341604

Motor side (plastic) 3-11/16"

Lid side (metal) 3-13/16"

Most people just use 4" I believe. HighTempSilicone.com sells some pretty cool reducers (4x3.75 etc.) if you want it to be extra special.

The OD on my NW90mm TB is right at 4".

Thank you very much!!! I would like someone to verify the MAF size, since the actual SLP MAF has plastic ends with no center air foil (If I'm not mistaken), so I could see a possible difference, although it is probably small.

Thanks again for the info

Can anyone confirm the MAF measurements?

Thanks, James.
