Which MAF sensor is this?

[Impala131]

Hey all,

I pulled this MAF sensor off of a 2001 Cadillac Deville (4.6L Northstar) . Looks like an LQ4 MAF from the photos I have seen, but I've been told that this model did not use the LQ4 MAF.

The number molded into the plastic reads 25168491.

The printed number above the bar code is 25168491.

The printed number below the bar code is 0213881A.

Thanks

Based on web searches and reading, this is the same MAF as an LS1 uses. So perhaps I need to start with an LS1 MAF table for tuning and adjust from there?

I found this http://fndpartsco.com/?product=2005-cadillac-deville-air-flow-meter-sensor-25168491-oem looks to be a factory N* maf.

-Edit- it looks like they used that same maf on a ton of vehicles. This part is compatible with 721 vehicle(s)
