No I don’t have the P/N off hand, but I know I’ve seen it on the AB website & ebay.

 

Your local auto parts store should have a bunch of o-rings in stock. You could take your air box lid in and match it.

Also Lowe's carries an assorted pack of large o-rings for like $5 or $10 that should have the right size or close enough.

 

Have at it

 

Ok, so I followed this thread and ordered just the MAF insert for my ‘04 D2.

Seems like I mistakenly ordered the Delphi AF10156.

What I pulled out of my MAF housing is a Bosch F 00C 2G2 029.

Same connector and mounting flange, but the Delphi insert is a little different than the Bosch.

Are they interchangeable? Does anyone know for sure? Best 4X4?

 

I've installed a few aftermarket Delphi units on customer D2/P38's. They worked when I installed them.

 

Granted, I did not install it. Don’t know if it’ll work - or not. Just saw that it was different and decided to clean the Bosch while I had it out and reinstalled. The Delphi insert had an additional wire/sensor.

 

Same Delphi P/N? AF10156

 

Delphi P/N: AF10383

 

However the P/N you list also shows as compatible. I think one supersedes the other.

 

The one pictured looks more like the Bosch insert. Maybe I'll grow a set and give the Delphi AF10156 a try.
