a few years ago i spent thousands trying to figure out what was the cause of what felt like running over railroad tracks when pulling in third gear . it came back a few days ago , cleaned my maf and its gone. but as i remember once it's dirty the cleaning only last a few miles so guess it's off the neillo porsche for a new maf , an ez fix

 

Agree buy new Bosch from reputable source.

 

Like RMC said get the OEM Bosch 0280218009 MAF from a reputable source. You may want to get it somewhere other than the dealer since the markup is considerable.

 

I'm superstitious and even tho the 986/996 are interchangeable? i'd order only the bosch 124-00 lol. it s 2 min replacement w a torx t20 and away you go!

"cleaning" mafs is for the birds.
