Good to know.
I replaced my MAF with a second-hand one off Ebay years ago - still have the old one and have been meaning to try cleaning it sometime (cos I've got nothing to lose, despite the numerous warnings that the Bosch MAFs can't be cleaned...).

ups, yes CRC MAF cleaner..

I've read that this is the only one good that should be used. I cleaned MAF 10.000 km before too and it worked good all the time.

I'll see now how it drives with cleaned MAF for the second time. I got feeling yesterday that it is doing some problems again, but there was no actually loss of power, maybe I just had some fears..

I also replaced the original manifold today and remove pre-cat, while installing sport header from OBX - for Nissan Sentra (QG18DE) and car drives different again, so I need to drive some more days if cleaning of the MAF was successful.

Anyone knows, if heat wrapping of the header / manifold is good as I see it's quite hot in the machine from the header when you stop driving. New header doesn't have an heat shield anymore now...

best

and this is how you can clean MAF - with a small brush (worked for an mechanic for 38 years):

or here, this guy is cleaning MAF's with Alcohol and says it worked for the last 12 years :)

I'll try to re-clean it like that as there is still some dirt on my MAF that doesn't go off with just CRC spraying...

let's see  :)
