hello guys.
well i have a check engine light on in my car, and i think the problem has to do with my MAF sensor. I was just wondering instead of getting the same audi s4 MAF, is there such thing as an upgraded one?
Should i just change it to a hitachi, or get the hitachi conversion?

 

fault code?

 

DUDE, don't throw parts at it, get the codes! You already have the Hitachi MAF. There are no gains in changing it to anything else, unless you go BIG turbo.

 

alright well in the future if i want to get big turbo. what would i ahve to upgrade too.. the rs4 maf. but to use the rs4 one i would need the rs4 air box... and would i be able to use my awe s-flo???

 

Do a search, we have beaten this to death. You would not use the RS4 MAF, just a bigger Hitachi, or stock MAF.
Yes, you need a bigger MAF for the RS4 airbox, & the S-flow will not work.
