Cleaning the MAF & IAT sensors

[tricache]

good write up Dan, had to do this a while ago when my intake started to leak and let in a stack of dirty air and thus dirt which coated the MAF sensor, car started running 20L/100kms just around town haha not good for a neo :P

For all you people with very new cars (under 10000km) it shouldn't be an issue, I wouldn't go cleaning it just because you can...

If you regularly get dealer servicing and you think it might be a prob get them to look at it/do it next service if it's not that far away.

Thanks for this. I did this last night and i must say after over 54000klms it feels like a rocket again.

Thanks heaps

Never heard of that one, interesting.

So here are my results...

Before and After Pics below-
So my car has done 58,000kms and it was very dirty!

My tools consisted of MAF Cleaner (same as CO Cleaner, just a tad cheaper actually) and a whisky and coke

I cleaned mine on friday and pull maf out this arvo just to inspect it, after one tank of fuel it was dusted again.
Cleaning the o2 sensor wont do anything spectacular but its worth a look some times just to see whats covering it.

I wonder if the cars with after market cold air intakes are affected as much? Anyone?
The standed setup picking up in the wheel arch is a nice dusty spot!

I know mine gets dirtier with the SRI setup, both with a dry filter (AEM) and oiled (K&N). That's the price you pay for a little more grunt and some woosh noise

Ohok, hmmm, did the maf sensor go back to just as bad black dusted??? Or was it still better than before you cleaned it originally?
