Well, 3" = 76.2 mm.

I THINK the stock MAF connection at the intake tube is 3-1/2" diameter. BUT the stock MAF is inside the airbox and it is the airbox that actually connects to the rubber connector.

I do know that 80mm MAF units require a rubber ring to upsize the diameter to fit the intake tube connector.
