I had won some MAS (mass air sensors) on ebay in a lot... after relisting the incorrect one for my van (got one for my 77 and one for 78-79's).

Needless to say the part number for my VW Westfalia MAS is
BOS-0-280-200-018

I decided to swap the one on my westy with the replacement one I had because the one on my car stuck and I thought it could have issues with effecting the running operation of the motor.

The part installed on mine was
BOS-0-280-200-020 however according to www.cip1.com the correct part number is the 018 MAS...

Now, I have the correct part on the van according to what cip1's site says is the correct part... Is there any negative side effects that could have been temporary or permenent with the incorrect MAS on it?

Just wanted to verify and make sure I'm good to go...

Thanks Jered
