is there a preferred method to clean the throttle body and air mass sensors?
also, which auto parts store sells a quality air filter?
thanks,

You shouldn't need to clean there MAF and not something I would do preventativly. Wipe out the throttle body and then let it adapt before starting (ignition on, wait 10 seconds or until you hear it clicking). I don't buy any maintenance products from local auto parts stores. OEM companies purchased online or the Porsche dealer. The only thing I get from those stores are bulbs and washer fluid.

Carb cleaner is fine. I wouldn't spray anything on the MAF.

CRC does make a MAF specific cleaner. It also works great to clean throttle-bodies. The only reason to use it on the MAF's is if you think they may be contaminated by something like oil vapors. Since they do come after the turbo's on the CTT there is that possibility. On other models if you keep after the air filter as scheduled the MAFs shouldn't get contaminated.

Oh - unlike most carb cleaners - the CRC MAF cleaner doesn't seem to leave any residue - which is a very good thing for the MAFs.

The MAF is before the turbo.

Is it? Haven't really looked but figured it would be about the same place in the intake as on the NA V8..

On both models they are draw-thru not blow-thru. The mafs can get dirty over time. I cleaned mine with the crc maf cleaner and noticed a difference @ around 100k. Always ran the factory paper filters.
