Descreen the MAF
Call me an old boring fart, but from my experience:
Rule 1: "Don't mess with the MAF"
It is just fooling the computer into beliveing something that is not true. Yes, I know it is a common mod to do on various cars, and with a lot of buggerising around one might get it correct. But the MAF is the most accurate sensor on the car telling the computer how much air the engine is digesting. Fiddling with something is effetcivley putting it out of calibration. If you put a less resticted MAF in AND tell the computer it's calibration - that is the best way.
Just my 2c. I can already see the flames leaping towards me
But until we have something better, who am I to argue!
Cheers,
Hymee.

After driving to work and back today (60km) the soot is back. It doesn't appear to be piling up as quickly as it usually does though.
Perhaps in my frenzied drive yesterday I was going so hard that I was spitting flames and burning the evidence?
Perhaps too Omicron is correct about the ECU learning and hence the a/f ratio is slowly returning to normal, along with the soot.

I agree. Some who have replaced the airbox and / or screens have experienced rough idle, due in part to the screens being removed. The turbulent airflow cause the rough idle.

If you have time to compare, I have some other ones prior to de-screening here:

I haven't compared yet, but will be doing so very soon!

Okay, for the love of God; DO NOT TAKE OFF BOTH OF THESE SCREENS! I tried it both ways and reset the ECU each time, giving the ECU some time to relearn some parameters. With just the first screen removed it works great, no change in idle or driveability. Without both, it is horrible. It won't idle for crap, and low end power went into the toilet. The idle would sit there and go up and down as the electrons ran around screaming "THE SCREENS ARE GONE! THE SCREENS ARE GONE!." Bottom line is, do not do this unless you have some way of messing with the ECU. What I want to know is how the intake manufacturers are getting around this? Are the aftermarket pipes the same as the factory pipes? Or are they a bit smaller? Perhaps they are able to have a longer straight section before the MAF. Any information?
