I am installing a LT1 MAF on a guys 87 GN and i was under the impression that they were a "plug & play" installation. I removed the original MAF and when installing the LT1 MAF I found it to be 1/2" larger than the inlet duct boot.
Is there an adapter boot that I need to use? I could probably source something locally here if needed, just wanted to know if this is a common problem with the installation.

And yes I have a translator box before anyone mentions it.

Thanks

Get a 3" mass air pipe and K&N filter to go with it.

GM part# 19112572 purchased directly from GM for a 94 Trans Am 5.7L
Actually GM used the same MAF on almost all V8's for that era on pre-LS motors.

Not the end of the world, i just have to find a 3" to 3.5" boot to connect to the inlet duct. the air filter went on with relative ease, just need to connect to the engine and mount the translator.

LT1 MAF and translator installed... what a difference in how the engine runs. It is much smoother and has incredible throttle response, and the engine is fully balanced so it now idles so smooth I can almost stand up a coin on the plenum at idle.

I have a Home Depot almost across the street from my house so that is where the adapter boot came from to connect the 3.5" MAF to the 3"inlet duct.

Who's car is this on? Is this Gord's car?
Yup... now I wish he'd answer his phone and come and get it out of my garage.
