RB20 MAF Size?

[Cpt_Impossible]

Hey, quick question:

Whats the OD of the RB20DET stock MAF? It looks like 3 inches but I don't feel like taking my setup apart to find out when someone can just tell me. I was told 2.5" but holding a 2.5" coupler next to it, it doesn't look that small.

I am planning on having a hard intake pipe made and want to have it all planned out before I go to the shop to have one fabbed.

Thanks

pretty sure it's 3" just like the RB25DET and Z32 MAF is. You don't need to remove it to measure it, just use vernier calipers.

and the turbo inlet is 2.5" right? See, I made a cold air box and the intercooler pipes are in the way, i cant really fit a caliper in there right now.

Here I just updated my chart, to show the sizes for each MAF and also the Wiring for the CA18/Q45
