94-96 MAF Sensor Outer Diameter Spec

Hey all,

Can anyone with a 94-96 LT1 or LT4 really quickly measure the outer diameter of the MAF sensor were the intake ducting slips over?

I am trying to figure out if an 86-89 TPI MAF would correctly interface with the ducting that goes on either side of the 94-96 MAF sensor.

Thanks!

Bump!

Hoping someone might be able to take a few min this weekend to take this measurement!

I would but I don't have a 94-96 MAF car nor the parts to measure the dimensions from!

Thanks!

How about a new on the shelf at a 'local' supplier?

To my eye, it appears to be right at 3-5/8".

Needs to be a bit more accurate than your 'Eyescope' to be of value to the OP!

Yeah, I totally get your comment, but I'm unfamiliar with these clamps and how to remove/install them...

...so I did my best to give the OP some hopefully useful data. I just very carefully re-measured the MAF housing inlet diameter, looking straight down from above, and I'm confident that my eyescope reading of 3-5/8" is within a 1/16". If the OP's MAF diameter is significantly different from this (say, 3-3/8", or 3-13/16", or...), then my measurement should be of value to him.

OEITKER clamp and in the past this ( OEITKER P/N 16700092) was mentioned to be correct but OEITKER has some very interesting options and dependent on the vendor minimums might not be an issue. The 293 style from them looks interesting.

A different part number mentioned in that thread seems to be available from many vendors as inexpensively as $1.39 plus of course the ship. Do your own research!

Thanks @WVZR-1 for the info. Over the several months I've been skulking about here on the C4 forum I've been building a "Helpful Corvette Links" database on my computer, and just added the above links to it for future reference.

Thanks again.

Anyone could check diameter of the MAF with a 'local' - that sensor has GM applications through probably 2004 and a person might find both metallic and plastic/composite versions of it. OE from GM I believe was serviced with clamps earlier years. Later I doubt that.

Okay found a local O'Reilly that had a 1995 Vette MAF sensor in stock. Bad news is that the dimensions don't match the 1985 sensor that I have. Good news is that it doesn't appear too far off.

I measured 3.65" inlet and outlet OD of the sensor.
