Yeah.
Pontiac says it's 75mm... Not that they know anything about it... The actual measurement is 78mm.
I HIGHLY recommend the Lingenfelter. I've been running it with my uber top end now for the past few weeks and it's been great. With the car un-tuned, I needed something to relax the decay rate of the idle, it was all but stalling on me at stop lights and in U-turns.

Lingenfelter 100mm MAF.

FYI;
"This MAF sensor will NOT work with stock engine programming and requires recalibration of the factory PCM or ECM. The proper starting MAF sensor curve for most GM applications is supplied with the sensor but you will need EFILive, HPTuners, LS1/LT1/LS2 Edit, TunerCat or other similar software programs to recalibrate the MAF curve or have it done for you by a tuning shop or custom calibration company. The proper curves can be downloaded from the Lingenfelter web site under downloads > product instructions.

This MAF sensor is 4.00 inch outer diameter and 4.00 inches in length. Custom ductwork will be needed to install this in most vehicle applications and is not included. You can purchase the universal adapter harness with 12 inch leads that can be hard wired into any system or you can choose one of our plug-and-play adapter harnesses that are available for most applications"

Enjoy.
