opening the box on top leads right to them.
it doesn't nothing to open it up...blow them off or spray them with whatever and put it back on.
I rode around for months with a dirty MAF thinking it was something else...the damn guy takes a can of air, sprays the MAF and bam, like a brand new car. I felt so retarded...
Anyway its not hard to clean and I seriously doubt u could break something in there...unless you try really hard.
