How to install LS3 Corvette MAF
Thanks for the MAF offer Mark. I have a 89mm ID tube that I am going to try. My theory is that 85 is too small, and 100 is too big. I want to keep the diameter small enough to keep the velocity up, without restriction, that's why I chose 89mm. This is where I am going to start tuning from. The challenge is; how hard is it to tune the MAF, and then what are the dyno numbers.
I am thinking this 4" ebay silicone hose will clamp onto my ly6 throttle body and the other end can clamp onto a 4 inch aluminum tube where I'll weld or epoxy the maf sensor bung. That will run close to the fender where colds air is accessable and I could install a filter.
There doesn't seem to be enough info on this subject here. Is there somwhere I need to install a vacuum line on the cold air intake?

What material is that MAF mount made from? Aluminum?
From the instructions above:
Mass Air Flow (MAF) Sensor
NOTE: It is critical that the MAF sensor is mounted per the
instructions below. Vehicle performance and/or driveability may
be affected if it is not mounted as recommended.
The mass air flow sensor must be installed in the induction
system using the supplied MAF sensor mounting boss. The
induction system should be 4 inches in diameter and have a
minimum straight section 6 inches in length. Mount the MAF
sensor in the middle of the straight induction section, ensuring
that the middle of the mounting boss is at least 10 inches from
the throttle body.
The MAF sensor must be oriented correctly in the induction
system – note the arrow on the sensor indicating flow
direction. Be sure to weld the mounting boss correctly –
the sensor will only mount one way in the boss (see diagram).
Weld the boss in place before installing the sensor.
When installed in the vehicle, the MAF sensor should be
mounted with the connector end pointing between horizontal and
fully upright – do not mount with the connector oriented downward.

I'm pretty sure it's aluminum. Thanks for the instructions. I think elsewhere in the instructions they mentioned 4 inch pipe and by the curve on that bung, that seems about right. I just feel like I'm missing something.

so is it ok to mount the Ls3 MAF sensor in a 89mm tube?..... even though they say to do in a 4" tube?.... the 3.5" tube is the only that will fit in my setup to get a long enough pc in there to get a smooth flow?... should be able to be tuned to work ,,, right?
bumping this thread for clarification. I am trying to figure out what pins need to move around in my connector on my LQ4 harness. MAF is same as above in this thread.

Hi,
I am looking for a pigtail to go from the ls7 maf to the 02 corvette 5 pin with a break out pigtail for the iat sensor.
Thanks
